Help me with this, I’ve been stuck in it for a long time

See the explanation below please :)

Step-by-step explanation:

a. There is always one spuare on both the top right and bottom left corner, but the number of squares in the center part is always (For example: first: =1, second: = 4, third: = 9, etc.)

b. It is quadratic since the total number of squares in each figure equals +2

c. Sub n=1, n=2, n=3, n=4 into +2 and prove the pattern fits

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

answer4 to the second power is 16

and 4 to the third power is 64,
