Answer:

51

Step-by-step explanation:

when n=1

<h2><u><em>t 1=1 </em></u></h2>

<u><em>when n=2</em></u>

<u><em>t2=4</em></u>

<u><em>as first term is 1 and second term is 4 so the common difference is 3 ,for 6 term if you put this in formula for sum to the n term you will get 51 </em></u>

<u><em>t1 =1</em></u>

<u><em>d=3</em></u>

<u><em>n=6 </em></u>

<u><em>than S6=51 </em></u>
