What is the sum of the geometric series 20 + 21 + 22 + 23 + 24 + … + 29?
a) 1,023
b)511
c)2,407
d)1,012

The answer is a) 1,023

Step-by-step explanation:

A geometric series is a series with a constant ratio between successive terms. So, the given series must be in the exponential form.

We have been asked about the sum of the geometric series :

Sum = 1023

Hence, option A is the answer.

The given series : 20+21+22+23+....+29 is an arithmetic series.

Its sum is :

I have solved the question both ways. Both the answers are right with respect to the series name.
