The geometric sequence is a sequence in which the proceeding number is equal to the preceeding number multiplied by a ratio. The expression that represents this sequence is an = a1*r^(n-1) where r is the ratio and n is an integer. This type of formula is exponential
Two other ways to name plane V are
plane ANCRMX
plane XMRCNA
m + 4 = 5m - 12
Subtract m from both sides.
4 = 4m - 12
Add 12 to both sides
16 = 4m
Divide both sides by 4
m = 4
