Correct option is A
Given series: 40, 48, 41, 16, 42, 8, 43, ?
Odd positions: 40, 41, 42, 43
These numbers increase by 1 in each odd position.
Even positions: 48, 16, 8, ?
These numbers appear to be halving:
48 ÷ 3 = 16
16 ÷ 2 = 8
Continuing this pattern,
8÷1=8.
So, the missing number in the series is:
Correct answer: (a) 8
