2. A geometric sequence of positive integers is formed for which the first term is 2 and the fifth term is 162. What is the sixth term of the sequence?
2) first term is 2 which is multiplied by the common ratio 4 times to get the 5th term = 162
2 * r4 = 162
r = 3
to get from the 5th term to the sixt term multiply by the ratio, 3 162 x3 = 486
