Why, that's just 6 times the sum of the numbers from 1 to 50 !
The sum of the numbers from 1 to 50 is:
1 + 50 = 51
2 + 49 = 51
3 + 48 = 51
4 + 47 = 51
5 + 46 = 51
.
.
.
etc. There are 25 pairs, and each pair sums to 51. So the sum of 1 ... 50 is (25 x 51) = 1,275.
The sum of the first 50 multiples of 6 is (1,275 x 6) = 7,650.
The first 50 multiples of 6 are the first fifty even multiples of 3.
90
It is: 6+12+18 = 36
25, 50, 75, 100, 125, 150
All multiples of 12 are also multiples of 6 and they all can be written as the sum of nine numbers.
5 + 10+15+20=50 ans
The first 50 multiples of 6 are the first fifty even multiples of 3.
90
It is: 6+12+18 = 36
The sum of three consecutive multiples of 6 is 666, the multiples are 216, 222 and 228.
1 x 6 = 62 x 6 = 12The sum of 12 + 6 = 18
6+12+18+24+30=90
6 + 12 + 18 + 24 + 30 + 36 = 126
The first 6 multiples of 9 are 9, 18, 27, 36, 45 and 54. Their sum (total) is 189. In other words, 1x9 + 2x9 + 3x9 + 4x9 + 5x9 + 6x9 = 21x9 = 189.
It is 751500.Here's the first ten.6, 12, 18, 24, 30, 36, 42, 48, 54, 60
25, 50, 75, 100, 125, 150
10, 20, 30, 40, 50, 60.
