Show answer & explanation
Correct answer: D
Explanation
The correct answear is option 4 i.e 1964
Given series: 1.5, 2, 3, 6, 18, 108, 1964
The logic used here is:
1.5 x 2 = 3
2 x 3 = 6
3 x 6 = 18
6 x 18 = 108
18 x 108 = 1944
So, 1964 doesnot belong to the series.
Hence, option 4 is the correct option.
