Add these 6 numbers together to find your first hour.

Keep doubling the preceding number to find the other two answers.

**Reiny**, Monday, March 14, 2011 at 5:37pmyour numbers form a geometric sequence where

a = .02

r = 2

Term(6) = ar^5 = .02(2^5) = .02(32) = .64

term(10) = ar^9 = .02(2^9) = .02(512) = 10.24

ar^(n-1) > 5.00

.02(2)^(n-1) > 5

2^(n-1) > 250

I know 2^7 = 128 and 2^8 = 256

so what do you think?
