See how in the equation they put n into the x spot:
They changed the variable names:
Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:
When they say, 13 term, they mean which would be the 13th answer in the series. So the first term would be based off of
So whatever number is in the n position by a is what you'll be plugging into the x spot.

Answer:
144 square inches
Step-by-step explanation:
Total surface area of the rectangular prism = Sum of all the area of its sides
Since it has a square base which can be covered by 16 squares of length 1 inch each, then;
length of its base = 4 inches
So that,
i. Area of its base =
=
area of its base = 16 square inches
ii. Area of one of the surfaces of its sides = length x width (or base x height)
= 4 x 7
= 28 square inches
Sum of the area of its vertical sides = 4 x 28
= 112 square inches
Thus,
Total surface area of the prism = 16 + 16 + 112
= 144 square inches
