4. mukushla Group Title

in GP each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio

5. mukushla Group Title

for example here$18=54\times\frac{1}{3}$$6=18\times\frac{1}{3}$...

6. mukushla Group Title

so the common ratio is $r=\frac{1}{3}$
