Consider the geometric sequence 3, 9, 27, 81, .... Find the eighth term of the sequence. Express your answer as a common fraction.
81 * 3 * 3 * 3 * 3 * 3 = .........
81 * 35 =............
Check your arithmetic. That would be the 9th term.
Yep....thought it said ninth when I was answering.... thanx for the notice !
YW, but your methodology was correct versus mine. I think I made a mistake when I "rewrote" the sequence. I think I converted it to an exponential sequence rather than a geometric sequence. I'm not sure of that, though.

Let's write that same sequence as 31, 32, 33, 34, ...
so the eighth term would be 38 which is 6561.
