Question

The first term of a geometric sequence is 2 and the common ratio is -3 find the fifth term

Answer 1

Answer:

With geometric sequences, all you have to do is multiply each term by -3 until you get to the needed term.

First term: 2

Second term: 2 * -3 = -6

Third term: -6 * -3 = 18

Fourth term: 18 * -3 = -54

Fifth term: -54 * -3 = 162

The fifth term of the sequence is 162.
