The geometric rule for the nth term of the geometric sequence for which a1 =−6 and a5=−486 is -6 × 3^(n - 1)
<h3>The nth term of a geometric sequence</h3>
First term, a1 = -6
Fifth term, a5 = -486
a5 = ar^(n - 1)
-486 = -6 × r^(5-1)
-486 = -6r⁴
r⁴ = -486 / 6
r⁴ = 81
r = 4√81
r = 3
Geometric rule:
nth term = ar^(n-1)
nth term = -6 × 3^(n - 1)

Answer:
42 ft
Step-by-step explanation:
18 plus 24 equals 42 feet
To find the mean you first add all the numbers up you get each day
12+16+0+8+31+28+17=112
Than you divided it by how many days there are...
112/7=16
So the mean is 16
