(a) 216 (b) 162 (c) 108 (d) 54 (e) 27 Answer by Edwin McCravy(20056) (Show Source):
You can put this solution on YOUR website! If a geometric sequence starts with a first term of 2 and grows exponentially by a factor of 3, what is the sum of the 4th and 5th terms?
1st term = 2
2nd term = 6
3rd term = 18
4th term = 54
5th term = 162
4th term + 5th term = 54 + 162 = 216, choice (a)
