A Correct answer
Explanation

When we observe the series, 34 - 16 = 18.18 - 8 = 10 [Since previous difference number is 16, so 16/2 = 8. Now, 8 is to be subtracted from the previous number, i.e. 18.]10 - 4 = 6 [Here, previous difference number is 8, so 8/2 = 4. Now, 4 is to subtracted from previous number, i.e. 10.]Next difference number = 4/2 = 2.So, 6 -2 = 4.Next difference number = 2/2 = 1. So, 4 - 1 = 3.
