Dear peachgal,

Let me give you an idea, the denominator is always one greater than the numerator. (i.e: Numerator+1=Denominator) Therefore when you are writing the general term if the numerator is n then the denominator should be n+1. Now consider what the first term of the sequence is, that is when n=1 the numerator and denominator must be 2 and 3 respectively.

Hope you can continue.

Hello, peachgal!

Another view of the sequence . . .

Find the formula for , the genereal term of: .

The numerators are even numbers:

. .


The denominators are one more than the numerators:
