Answer 2

Answer:

=155

Step-by-step explanation:

Given AP = 2,5,8,..........

  Here, First term (a) = 2

common difference(d) = 5-2 = 3

Number of terms = 10

By using formula;-

                                 $s_{n} = \frac{n}{2}(2a+(n-1)d)$

                                 $s_{10}$ $= \frac{10}{2}(2(2)+(10-1)(3))$

                                      $=5(4+27)$    

                                      $=5(31)$

                                      $=155$
