Question

In the following question, select the missing number from the given series.
1, 16, 31, 46, 61, ?

A.

78

B.

70

C.

76

D.

80

Correct option is C


16−1=15
31−16=15
46−31=15
61−46=15
The difference between each consecutive term in the series is 15. Thus, the pattern involves adding 15 to each term to get the next term.
Now, add 15 to the last term (61) to find the missing number:
61+15=76
Hence, the missing number is 76.
Hence, option (c)is the correct answer.
