What should come in place of the question mark (?) in the given series? 28 34 44 58 76?

A114

B91

C97

D98

Answer:

D. 98

Read Explanation:

Let’s find the pattern:

Series:
28, 34, 44, 58, 76, ?

Find differences

  • 34 − 28 = 6

  • 44 − 34 = 10

  • 58 − 44 = 14

  • 76 − 58 = 18

So differences are:
6, 10, 14, 18 → increasing by +4 each time

Next difference

Next = 18 + 4 = 22

Add to last term

76 + 22 = 98
