Answer:
Step-by-step explanation:
It's geometric. The nth term differs by -5 when compared to the n+1 term.
Sum 0 to n a(-5)^n-1 where a = 2
I think this is what you want, but there is also a formula. See below.
Sum = a (r^n - 1)/(r - 1)
So 84%=1050
what is left is 100%-84%=16%
equal ratios
1050 to 84=x to 16
1050:84=x:16
fractionify
1050/84=x/16
multiply both sides
by 16
16800/84=x
simplify
200=x
answer is 200 is left
