Answer:
The first choice is correct.
Step-by-step explanation:
First work out the common ratio r:-
a2 = a1r and a5 = a1 r^4
So r^3 = a1r^4 / a1r = 256/ 108
r = cube root (256/-108) = 4/3
So the explicit formula is 108(4/3)^(n-1)
Assume he played x games in total.
So x * 60% = 12
->x = 12 / 60% = 20
Is This A Good Or Bad Thing?
X-4+x=20
2x=20+4
2x=24
X=12
Number is 12 because 12-4 is 8 and 8+12 is 20
Answer:

Step-by-step explanation:
So we have the equation:

First, let's subtract 9 from both sides:

Divide both sides by -4:

Add 1 to both sides:

Divide both sides by 2:

And we're done!
