    Try using the arithmetic progression equation?



    Tn is the nth term,
    a is the first term,
    n is the term number in the sequence (n = 1 means first, n = 2 means second, etc)
    d is the common difference (the difference between any two consecutive terms).

    Can you work it out? :)

    Tn=10n
    where Tn is the nth term
