write down the terms indicated in each of these arithmetic series.

$\frac{1}{4} + \frac{7}{8}........;12th, nth$

I worked out what the 12th term is, $7\frac{1}{8}$ using this formulae $a + (n-1)d$

but I am not sure how to work out the nth term? do i use the same formulae?

yes put 1/4 as "a"
and 5/8 as "d"
