You were told the sum of the first 4 terms is 22, so:

You were told the sum of the first 5 terms is 35, so you can solve for the 5th term:

35-22 = 13, so

Now you have two equations and two variables.

Substitute this into the first equation

And substitute this back into either equation

So now you have your values:

The pattern should be rather obvious:

So
