Question

What should come in the place of question mark (?) in the given series 208 190 163 127 82 ?

• A. 28
• B. 54
• C. 45
• D. 12

Answer 1

Answer:

A. 28

Let’s look at the differences between the numbers: 208 → 190 = −18 190 → 163 = −27 163 → 127 = −36 127 → 82 = −45 Now observe the pattern in the differences: 18, 27, 36, 45 These increase by 9 each time. So the next difference should be: 45 + 9 = 54 Now subtract it from 82: 82 − 54 = 28
