Try using the arithmetic progression equation?

$T_n = a + (n-1)d$

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
