What should come in the place of question mark (?) in the given series 208 190 163 127 82 ?
A28
B54
C45
D12
Answer:
A. 28
Read Explanation:
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
