Okay. Basically, a is greater than or equal to 9.
First, you do distribute the 2.
8a+2-10a(< or =)20
Subtract two on both sides.
8a-10a(< or =)18
Then subtract 10a from 8a
-2a(< or =)18
Divide by two on both sides
and switch around the greater than sign since you divided by a <span>-2
</span>a(> or =)-9
<span>And if you check, -9 works, -8 works, and -10 doesn't work.</span>

Answer:
Recursive equation
and
where, n = 1, 2, 3, 4, ........ .
Explicit equation
.
Step-by-step explanation:
The given series is an G.P. series and the common ratio is 0.75.
Now, the terms are 20, 15, 11.25, .......
Therefore, the explicit equation of the series will be 
Again, the recursive equation of the given G.P. series will be
and
where, n = 1, 2, 3, 4, ........
