All the multiples of 5 between 1 and 51 are:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
These add up to 275.
51 + 57 = 108
45, 48, 51, 54, 57, and 60 are.
The multiples of 51 (which are infinite) are all divisible by 51 , including these: 102, 153, 204, 255, 306, 357, 408, 459, 510 . . .
51
n + 51
Without a specific number, all of the numbers in that range are multiples.
51 + 57 = 108
They are 34 and 51.

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 = 512 + 49 = 513 + 48 = 514 + 47 = 515 + 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 sum of the numbers between 51 and 150 is equal to 10050 - or 50 x 201 - as there are 50 lots of 201 in the sum.

Multiples of 51
17, 34, 51, 68, 85
45, 48, 51, 54, 57, and 60 are.
The multiples of 51 (which are infinite) are all divisible by 51 , including these: 102, 153, 204, 255, 306, 357, 408, 459, 510 . . .
They can be: 51, 102, 153 and 201 which are 4 multiples of 51
