Answer:

Step-by-step explanation:
Explicit formula is used to represent all the terms of the geometric sequence using a single formula.

Here, a is the first term.
r is the common ratio.
r = second term ÷ first term
4, 8,16,32,64,.....
a = 4
r = 8 ÷4 = 2



(6x+5)^2 because both brackets have to have a plus in the middle to make the 25 positive and (6x5)x2 equals 60

The answer is 8r/9
2r = 5s/2 - s/4
2r = 10s/4 - s/4
2r = 9s/4
4 x 2r = 9s/4 x 4
8r = 9s
8r/9 = s
