Answer 2

Answer:

(A) 261  

Step-by-step 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.
