Find an explicit formula for the geometric sequence 3,15,75,375
a(n)=

an = 3(5)^(n-1).

Step-by-step explanation:

15 / 3 = 5

75/15 = 5

375/75 = 5

So the common ratio is 5.

First term a1 =3

an = a1 r^(n-1) is the explicit formula.

so here we have:

an = 3(5)^(n-1).

the answer is 45 i just did it on oddesy ware

constants mean the stopped points or the points on a graph that nothing is changing, hope this
