Consider the geometric sequence 3, 9, 27, 81, .... Find the eighth term of the sequence. Express your answer as a common fraction.
3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 3 8 =__________________ ( it is NOT a common FRACTION)
The common ratio is 3, so for the eight term you find 3^8, as the first term also 3. 3^5=6561.
