Answer: X=36
Step-by-step explanation: 5x = 180
X= 180/5
36
Should be %50 because half of all numbers are even and half are odd (don’t quote me on that though)
Formula: an = a1(r)^n-1
n = term number
a1 = first term
r = rate
Plug our values in:
n = 4
a1 = 15
r = 1/3
a4 = 15(1/3)^4-1
a4 = 15(1/3)^3
a4 = 15(1/27)
a4 = 0.5555555556
a4 = 0.6 to the nearest tenth
