What is the fifth term of the geometric sequence?
5, 15, 45, ...
a. 1,215
b. 1,875
c. 405
d. 3,645
The geometric sequence has a common ratio of 3. To find the fifth term, we can multiply the fourth term (45) by the common ratio.
45 * 3 = 135
Therefore, the fifth term of the geometric sequence is 135.
None of the answer choices (1,215, 1,875, 405, 3,645) match the result, so there may be a mistake in the given sequence or answer choices.
