Question 1175521
.
<pre>

Arithmetic progression with the first term   {{{a[1]}}} = 5  and common difference d = 5.


The general formula is


    {{{a[n]}}} = {{{a[1]}}} + (n-1)*d = 5 + (n-1)*5 = 5 + 5n - 5 = 5n.


<U>ANSWER</U>.   The general term is  {{{a[n]}}} = 5n.
</pre>

Solved, explained and completed.
