In the following question, a number series is given, after the number series, a number and then A, B, C, D and E are given. Complete the number series starting from the given number based on the pattern of the original number series and choose correct option. 31 33 39 63 183 903 25 A B C D E What will come in place of ‘D’? Correct Answer 177
Solution:
The pattern of the original number series is:
⇒ 31 + 2! = 33
⇒ 33 + 3! = 39
⇒ 39 + 4! = 63
⇒ 63 + 5! = 183
⇒ 183 + 6! = 903
According the pattern of the above series the number series starting from the given number
would be as:
⇒ A = 25 + 2! = 27
⇒ B = 27 + 3! = 33
⇒ C = 33 + 4! = 57
⇒ D = 57 + 5! = 177
⇒ E = 177 + 6! = 897
∴ The required number in place of D would be 177
