Answer 7

given a sequence: a1, a2, a3 .... an;
for n= 1,2, 3 . ..

here each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio(r)

Answer 8

The general form of a geometric sequence is
a,\ ar,\ ar^2,\ ar^3,\ ar^4,\

Answer 9

where r ≠ 0

Answer 10

okay that makes sense so i would multiply my a1 term by my r term?

Answer 11

yes but remember the next term is:\[a _{n+1} = a _{n}*r\]
