Question

What should come in place of the question mark (?) in the given series? 35 43 53 65 79?

• A. 95
• B. 112
• C. 103
• D. 107

Answer 1

Answer:

A. 95

Let’s find the pattern in the series:

35, 43, 53, 65, 79, ?

Find the differences

43 − 35 = 8
53 − 43 = 10
65 − 53 = 12
79 − 65 = 14

The differences are increasing by 2 each time:

8, 10, 12, 14

Next difference should be:

16

Add 16 to the last number

79 + 16 = 95

Final Answer:

95
