You're expected to recognise that this is an infinite geometric series .... |
Thanks. I have been working on it as a geometric sequence, but cannot figure out what n is. I have to find n before I can find the sum of the geometric sequence.
so a(base n) = a(base 1) (r^n-1)
2=1/8(2^n-1)
divide both sides by 1/8
1/4=2^n-1
and now I am stuck. I feel stupid, but I can't figure out how to get n from here. Any thoughts?
