If the first term of an arithmetic sequence is 10 and the 13th term is 58, what is the common difference?

  • arithmetic - ,

    The nth term of an arithmetic progression is defined by
    n = a + (n-1)d where,
    n = the nth term
    a = the first term
    d = the common difference

    Therefore,
    58 = 10 + (13 - 1)d
    48 = 12d
    d = 4
