Question

find how many integers between 200 and 500 are divisible by 8

Answer 1

37 integers between 200 and500 are divisible by 8.

Answer 2

Answer:

first no. mulitple of 8 is 200

so a = 200 , d=8 ,  an term = 496

so ,   an = a+(n-1)d

        496= 200 +(n-1)8

         296/8= n-1

          37+1=n

            n=38

         therefore, sn =n/2 (a+l)

           sn = 38/2(200+496)

            sn = 19*696

            sn= 13224
