Write an
explicit formula for
then
th
an.
term of the sequence 45, 15,5.

The sequence above is a geometric sequence

For an nth in a geometric sequence

where n is the number of terms

a is the first term

r is the common ratio

From the question

a = 45

r = 15 / 45

The explicit formula for the sequence is

U(n) = 45(1/3)^n-1

Hope this helps you

494.5 square inches

Step-by-step explanation:

5 times 4.3 is 21.5

21.5 times 23 is 494.5
