One of the things we learned this week in Precalc 11 is Geometric Sequences. It is a sequence of numbers where each term is found by multiplying the last term using the common ratio.
To find the common ratio, we can use the formula dividing a term by the previous one.
Ex.
3, 6, 12, 24, 48,….
To find we can use the formula Where a=
To find n we can use the same formula.
