Question

Please help? Will give fan and medal.

Write an explicit formula for the following sequence. Then generate the first five terms.
a(1) = 1250, r = 0.2

The explicit formula for the sequence is a(n) = 1250 * (0.2)^n-1 for n less than or equal to 1.

The first term is 1250.
The second term is 250.
However I don't know what the next three terms are, nor how to find them.

Thank you in advance! :)

Answer 1

for a2
use a2=1250*(0.2)^1

Answer 2

I've already found a2. I need to find a3, a4, and a5.

Answer 3

a3=50
a4=10

Answer 4

a5=2

Answer 5

I actually just found that out for myself lol thank you though!!!

Answer 6

good.
