Answer :
This would be a series: 5 + 10 + 15 + 20 +...+ 500
there are n terms → n = 100
the nth term is 500
there are n terms → n = 100
the nth term is 500
sum = (n/2)(a+b) in which n=number of multiples a =
value of first multiple b = value of last multiple So : (100/2) X
(4+400) 50 X 404 20200 The final answer is 20200. You got it?
