Answer 1

do you know what mean geometric sequence ?

Answer 2

given that the 3rd term is 16 and the 5th is 256 and given that there are 7 term in this geometric sequence

Answer 3

do you know this formula of geometric sequence

a_n = a_1 *r^(n-1)

where a_n = nth term
a_1 = firs term
r = common ratio
