Suppose Mary's followers triple every month.
After 0 months, she has 8(3)^0 = 8 followers. After 1 month, she has 8(3)^1 = 24 followers. After 2 months, she has 8(3)^2 = 72 followers. In general, after k months, she has 8(3)^k followers. So after 1 year (or 12 months), Mary has 8(3)^12 = 4,251,528 followers. |
