Answer:
No they are equivalent
Step-by-step explanation:
3/7 =21/35
3/5=21/35
Rewrite the whole number as a fraction. To rewrite a whole number as a fraction, simply place the whole number over 1. ...Multiply the numerators of the two fractions. ...Multiply the denominators of the two fractions. ...Simplify.
Given the recursive formula, each terms is five time the previous one.
This means that:
is 5 times
, which means 
- in turn,
is 5 times
, so we have
. This means that 
- Finally,
So, substituting this back gives

In general, since you have
, each time you compute a new term you multiply by a factor of 5, so if
, you have

The equivalent expression of
is
