Answer:
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

Answer:
the answer is hours
Step-by-step explanation:
so first we have to turn the fractions into mixed fractions, in order to do that we multiply the whole number by the denominator and add the numerator, our answer becomes the new numerator over the same denominator.
3 x 4 + 3
12 + 3
15
we do the same thing again.
1 x 3 + 1
3 + 1
4
then after we get our mixed fractions we subtract them from each other. Since the denominators are not the same we multiply to get the same denominators.
we subtract the numerators and keep the denominators.
then we simplify.
