Question

[2 ^ - 1 + (1/4) ^ - 1] / (2 ^ 1)​

Answer 1

Let’s find the pattern first . First number is 2 and the second number is 1. Second number is obtained when we divide first one by 2. So is the case with all other numbers in the series .

1st term - 2

2nd term - 2/2 = 1

3rd term - 1/2 = 1/2

4th term = 1/2 / 2 = 1/4

5th term = 1/4 /2 = 1/8

So the answer is 1/8.
