Question 1035975

What is the nth term for the following sequence please:  250, 280, 310, 340 and 370.

Also other than actually working it out logically and time consumingly, what is the 10th term of the above sequence, thank you very muchl.
<pre>This is an AP, and the formula for a term in an AP = {{{a[n] = a[1] + (n -1)d}}}, where:
{{{a[n]}}} = A specific term, or term "n"
{{{a[1]}}} = 1st term in the series 
n =   the sequence Number
d =   The common Difference, or the difference between terms

In this case, {{{a[n] = a[1] + (n - 1)d}}} becomes: {{{a[n] = 250 + (n - 1)30}}} =======> {{{a[n] = 250 + 30n - 30}}}
nth term, or {{{a[n] = 220 + 30n}}}
{{{a[10] = 220 + 30(10)}}} ------ Substituting 10 for n
10th term, or {{{highlight_green(a[10] = 520)}}}
