Answer:

(A) 261

Explanation:

We have to find the sum of summation of 3i+2 from i equals 5 to 13, that is


\sum_(i=5)^(13)(3i+2)

=
3(5)+2+3(6)+2+3(7)+2+3(8)+2+3(9)+2+3(10)+2+3(11)+2+3(12)+2+3(13)+2

=
17+20+23+26+29+32+35+38+41

=
261

Thus, the sum of summation of 3i+2 from i equals 5 to 13 is 261.
