Step-by-step explanation:

means a term can be found by multiplying previous term by .

So if we want to go backwards to find the previous term from a term that comes after it we need to multiply that by .

This means:

implies .

implies .

Another way to look at it:

Multiply both sides by 3:

By the symmetric property:

So if :
