Answer:
781250
Step-by-step explanation:
We first need to find the common ratio
-10 /2 = -5
50 / -10 = -5
The common ratio is -5
an = a (r) ^ (n-1)
a9 = 2 ( -5) ^(9-1)
= 2 (-5)^8
=781250
So if brother was 10, 5 years ago, then 10+5=15, bro is 15 now
in 15 years, he will be 15+15=30 years old
If f(x) = 6x , then f(2) = 6(2) or f(2) = 12... simply substitute the argument in for the variable in your expression on the right.
