Question

Find the sum s8 for the geometric series 6+0.6+0.06+0.006+...

A) 6.6666666
B) 0.1
C) -0.00000001
D) 3

Answer 1

The very first piece, "6", makes all but one answer pretty silly.

Answer 2

Do you see any patterns? Geometric sum just means add all those numbers up!

Answer 3

So its A?

Answer 4

I figured it would be A because of the numbers, I just wasn't sure how to find it!

Answer 5

6 + 0.6 = 6.6
6.6 + 0.06 = 6.66
6.66 + 0.006 = 6.666

and so on....
