Answer 2

Answer:

multiples of 2 and 5 = multiples of 10.

sum= 12,750

Step-by-step explanation:

by using arithmetic progression,

a= 10, d=10, l=500,

l= a+(n-1)d

500 = 10+ (n-1)10

490 = (n-1)10

n-1 = 49.

n=50.

n=50, a=10, l=500

Sum(n) = (n/2) (a+l)

= (50/2)×(10+500)

= 25 * 510

= 12,750
