99, 80, 63, __?__35, 24, 15, 8, 3, 0

D.

38

Correct option is B

Series - 99, 80, 63, ? , 35, 24, 15, 8, 3, 0
Step 1: Find the differences between consecutive terms
99−80=19
80−63=17
The difference is decreasing by 2 each time:
63−?=15(Following the pattern of decreasing by 2)
The difference between the next terms should be 13:
35−24=11
24−15=9
15−8=7
8−3=5
3−0=3
Step 2: Check the missing number
The missing number must have a difference of 15 with 63.
So, 63−15=48
Final Answer:
The missing number is 48.
Correct Option: (B) 48
