8, 12, 21, 37, ?, 98
Detailed Solution & Logic
Correct Answer:
62
Given series:
8, 12, 21, 37, ?, 98
Let us find the pattern by differences:
12 − 8 = 4
21 − 12 = 9
37 − 21 = 16
Observe the pattern in differences:
$4 = 2^2$
$9 = 3^2$
$16 = 4^2$
So next differences should be:
$5^2 = 25$
$6^2 = 36$
$7^2 = 49$
Now continue the series:
37 + 25 = 62
62 + 36 = 98
98 + 49 = 147 (next term)
Thus the missing number is 62.
✅ Correct Answer: 62
