THEORY
In this chapter we will discuss all the questions based on number series. In this type of questions candidate have to follow a definite pattern throughout the series. The task for the candidate is to follow the pattern and to complete the given series with the best alternative or to find the wrong term in the series.
DIFFERENT PATTERNS OF NUMBER SERIES
Pattern 1: When the difference between the consecutive numbers is same/ constant or the number series is in arithmetic progression.a, a + d, a + 2d, a + 3d, a + 4d, ........, a + (n – 1)d. Where a is first term, d is the common difference
Ex 1: 24, 21, 18, ?, 12, 9.
Where the difference is -3, answer is 15
Pattern 2: Any constant number is added to the difference of the consecutive numbers and form a series.
Ex 2: 2, 4, 8, 14, 22, 30
Next No. is 32 as 2 4 8 14 22 32
2 (2+2) (4+2) (6+2) (8+2)
Ex 3: 3, 4, 6, 9, 13, 18, __, Answer is 24 because 3 4 6 9 13 18 24
1 2 3 4 5 6Pattern 3: Multiplication or division Pattern
When a series is multiplied or divide by certain constant.
Ex 4: 6174, 882, 126, ?. Answer is 18, the series is divisible by 7.
Ex 5: 1, 2, 3, 6, 9, 18, ?, 54 (a) 18 (b) 27 (c) 36 (d) 81 (e) None of these
Number Series Completion
ChapterChapter
Part A : Verbal Reasoning
2 Number Series Completion
Solution: The given series is in the pattern × 2, × 3/2, × 2, × 3/2, ×2,.....
So, the missing term is 18 × 3/2 = 27 Or
1 2 3 6 9 18 ? 54
+1 +1
1
+3 +3
1 × 3
+9 +9
3 × 3
+27
9 × 3
Ans: (b) 27
Pattern 4: When a series follows the following pattern add, multiply, add, multiply, add,.... or add, substract, add, substract, add,.... etc.
Ex 6: 4, 6, 12, 14, 28, 30, .....
Solution: 4 6 12 14 28 30 60
+2 ×2 +2 ×2 +2 ×2
60 is the next number
Ex 7: 8, 28, 116, 584, ? (R.R.B 2002) (a) 1752 (b) 3502 (c) 3504 (d) 3508 (e) None of these
Solution: The given series is in the pattern: × 3 + 4, × 4 + 4, × 5 + 4, ..... (8 × 3) + 4 = 28 (28 × 4) + 4 = 116 (116 × 5) + 4 = 584 (584 × 6) + 4 = 3508So, the missing term is 584 × 6 + 4 = 3508.Ans: Option (d)
Ex 8: 3 4 10 33 136 685 ? (a) 3430 (b) 4802 (c) 5145 (d) 4116 (e) 5488
Solution: In this particular Series, the pattern is-
3 × 1 + 1 = 4; 4 × 2 + 2 = 10; 10 × 3 + 3 = 33; 33 × 4 + 4 = 136; 136 × 5 + 5 = 685; 685 × 6 + 6 = 4116.
Hence option (d)
Pattern 5: Series with Square or cube or square root or cube root of the number.
Ex 9: 1, 9, 25, 49, ?, 121 (S.S.C.) (a) 64 (b) 81 (c) 91 (d) 100 (e) None of these
Solution: The given series consists of squares of consecutive odd numbers i.e 12, 32, 52, 72,.....
So, the missing term = 92 = 81
Ans: Option (b)
Pattern 6: TRIANGULAR NUMBER
When any number series is in the form a, a + (a +1), a+ (a+1)+ (a+2), a + (a+1)+ (a+2) + (a+3), ........., nth term
of the series be ( ) ( ) + +=
n n 1 15 15 1
2 2.
Ex 10: 1, 3, 6, 4, 15, 21, ...... find the 15th term of the series?
Solution : 15th term = ( ) ( ) + +
=
n n 1 15 15 1
2 2 = 120 where n = 15.

3Number Series Completion
Pattern 7: Product of the digits and summation with any constant, gives next number of the series.
Ex 11: 69, 55, 26, 13, 5 [Find the Wrong term of the Series] (a) 69 (b) 55 (c) 26 (d) 13 (e) 5
Solution: We found that the series contains each term is one more than the product of the digits of the preceding term. Thus (6 × 9 ) + 1 = 55, (5 × 5) + 1 = 26, (2 × 6 ) + 1 = 13, (1 × 3) + 1 = 4. Hence option (e).
Pattern 8: Difference Between the adjacent numbers increases by a constant number.
Ex 12: 2, 7, 17, 32, ..?……. (a) 42 (b) 52 (c) 47 (d) 27 (e) 62
Solution: In this particular series the gap between the numbers are 5, 10, 15, ...so the next difference must be 20. Than the next number be 52. Hence option (b)
Pattern 9: Percentage increasing and decreasing pattern
Ex 13: 105, 94.5, 103.95, 93.56, ..?... (a) 102.91 (b) 102.98 (c) 102.95 (d) 103. 91 (e) none of these
Solution: In this particular Series the numbers are arranged on percentage increase and decrease pattern. As first there is 10% decrease and than 10% increase..i.e 105 – 10% of 105 = 94.5, 94.5 + 10% of 94.5 = 103.95 ..and so on. Hence option (a) 102.91 is the very next number of the series.
Pattern 10: Division or Multiplication with increasing and decreasing numbers.
Ex 14: 51975, 9450, 2100, 600, 240, 160 ? (a) 80 (b) 120 (c) 320 (d) 240 (e) 300
Solution: The pattern is
? = 160 0.5 = 320. Hence Option (c)
Ex 15: 16, 12, 18, 40.5, 121.5, 455.625 ? (a) 2050.1125 (b) 2050.2125 (c) 2050.3125 (d) 2050.4125 (e) 2050.5125
Solution: The pattern of the above Series:
16 × 0.75 = 12, 12 × 1.5 (i.e 0.75 + 0.75 = 1.5) = 18, 18 × 2.25 (i.e 1.5 + 0.75 = 2.25) = 40.5, 40.5 × 3 (i.e 2.25 + 0.75) = 121.5, ......, 455.625 × 4.50 = 2050.3125. Option (c)
Ex 16: 4,18, 48, 100, 180, 294 ? (a) 448 (b) 424 (c) 436 (d) 460 (e) 412
Solution: The pattern is, here 3rd order difference is constant.
? = 294 + 154 = 448

10 Number Series Completion
1. (c) The given series is in the pattern + 4, + 8, + 12, + 16, ..........
So, the missing term = 41 + 20 = 61
2. (d) The given series is in the pattern ×1, ×2, ×3, ×4, ..........
So, the missing term = 24 × 5= 120
3. (d) The given series is in the pattern ×2 + 1, × 2 + 2, × 2 + 3,.......
So, the missing term = 59 × 2 + 4 = 122
4. (b) The given series is in the pattern (22 – 1), (42 – 1),.......... (82 – 1), (102 – 1), (122 – 1). So, the missing term is (62 – 1) = 35
5. (c) The given series is in the pattern ÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2. So, the missing term is 960 ÷ 5 = 192
6. Option(e) Series is 92, 83, 74, 65, 56, 47, 38
? = 38 = 6561
7. (b) Series is 23, 43, 63, 83, 103, 123, …..
Then, ? = 143 = 2744.
8. (a) The gap is of – 9
9. (e)
10. (c) the difference between the numbers increases by 1.
11. (b)
Answer with Explanation
12. (d)
6 × 5 – 4 = 26
26 × 5 + 4 = 134
134 × 5 – 4 = 666
666 × 5 + 4 = 3334
3334 × 5 – 4 = 16666
16666 × 5 + 4 = ?
? = 83334
13. (e)
? = 294 + 154 = 448
14. (c) The series is: + 22, + 32, + 42, + 52, + 62, …..
15. (e) The series is : 232, 292, 312, 372, 412, …. (Square of prime numbers)
16. (d) The series is × 1.5, × 2, × 2.5, × 3, × 3.5
17. (a) The series is × 4 – 1, × 4 – 2, × 4 – 3, × 4 – 4, ….
18. (b) The series is + 123,+ (123 × 2),+(123 × 3),+ (123 × 4), ….
19. (c) the difference of the numbers (+ 111).
20. (d) The difference of the number is (– 121).

1. (a) All nos. in the given series are squares of odd nos., except 1296
1296 = (36)2
2. (c) 13 + 14 = 27
14 + 27 = 41
27 + 41 = 68
41 + 68 = 109
68 + 109 = 117
So, 45 is the wrong number in this series.
3. (e)
4. (d) The series is:
+ 33, + 53, + 73, + 93, + 113, + 133, ………..
5. (d) 4 × 4 + (4 × 3) = 28
28 × 5 + (5 × 4) = 160
