consider the first term to be
.7(1) = .7
term 2 = .7^2 = .49
what term = .01
.7^n = .01
n ln .7 = ln .01
n = ln.01/ln.7 = 12.9
term 12 = .7^12 = .0138 > .01
term 13 = .7^13 = .00968 < .01
.7(1) = .7
term 2 = .7^2 = .49
what term = .01
.7^n = .01
n ln .7 = ln .01
n = ln.01/ln.7 = 12.9
term 12 = .7^12 = .0138 > .01
term 13 = .7^13 = .00968 < .01
