A) 32 sticks
Each time 5 sticks are added. So pattern 6 would have 25 stickers added to the original 7 sticks equaling 32 sticks
B)n=5x+7
18 = ab^2
60.75 = ab^5
from first equation:- a = 18/b^2
so
60.75 = (18/b^2) * b^5
60.75 = 18b^3
b = cube root (60.75 / 18)
b = 1.5
so a = 18/1.5^2 = 8
so the required equation is y = 8(1.5)^x
