-the first 10 multiples of 20 are 20,40,60,80,100,120,140,160,180, and 200. :)
Well, the multiples of 8 go "8, 16, 24...etc." The first four multiples of 8 over 20 are 24, 32, 40, and 48. i) 24 + 32 = 56 ii) 56 + 40 = 96 iii) 96 + 48 = 144 Therefore the sum is 144.
5 + 10+15+20=50 ans
-15
They are 10 and 20
