Question

find the sum of the first 30 terms in the series: 2,4,8,16,...

Answer 1

Answer:

930

Step-by-step explanation:

1) Once upon a time there was a bored kid in class who invented a super cool formula

This formula goes like this:

n(n+1)

where n= the sum of the first n numbers in a series

so

30(30+1)=30(31)=930

930
