    seqences help!

    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?
