An+1= 3n+3 +2
An+1 - An = <span>3n+5 -3n-2=3
An is aa arithmetic sequence
its sum is given by:
A0 +A1 +A2 + . . . + An = N(Ao + An) /2
where N = n-0=n
</span><span>S50= A0 +A1 +A2 + . . . + A50 = 50(Ao + A50) /2
</span>
S50 = 50(Ao + A50) /2
Ao=2, A50=150+2=152
S50= <span>50(Ao + A50) /2
</span>
finally
<span>S50=25*154=3850</span>
