One thing you'll notice is that it's an arithmetic progression with first term 2 and common difference 5 (it increases by 5 with each successive term.
The general formula for an arithmetic progression is given by:
T_n = a + (n-1)d
where a is the first term and d the common difference.
Can you now give the nth term? Post what you get! :)
