Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, … A. an = 45(3)n ; an = 3(an), a1 = 45
B. an = 45(3)n − 1; an = 3(an − 1), a1 = 45
C. an = 45(3)n + 1; an = 3(an + 1), a1 = 45
NEED HELP ASAP PLS PLS PLS HEL

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
