Evaluate the series 4+2+1+1/2+1/4 to s10

Step-by-step explanation:

4+2+1+1/2+1/4.....

WE need to find out the sum s10

first term is 4 and second term is 2

2/4 = 1/2

1/2= 1/2

1/2 / 1= 1/2

so common ratio is 1/2

The given series is geometric series

we use the sum formula for the geometric series

Where 'r' is the common ratio and 'a' is the first term

a= 4  and r= 1/2

Plug in the values in the sum formula'

Given n=10
