Heavy rain in Oxford caused the Brandywine Creek to rise. The creek rose three inches the first day, and each day twice as much as the previous day. How much did the creek rise on the fifth day?
(Use Geometric Sequence Please!!!!)

Answer:

48

Step-by-step explanation:

used a calculator

The amount of the creek rise on the fifth day will be 48 inches.

Let a be the first term and r be the common ratio. Then the geometric sequences will be

[tex]\rm a_n = a_1} \cdot r^{(n -1 )}[/tex]

Heavy rain in Oxford caused the Brandywine Creek to rise.

The creek rose three inches the first day, and each day twice as much as the previous day.

Then we have

a₁ = 3

r = 2

Then the amount of the creek rise on the fifth day will be

n = 5, Then we have

a₅ = 3 × 2⁽⁵⁻¹⁾

a₅ = 3 × 2⁴

a₅ = 3 × 16

a₅ = 48 inches
