51 + 57 = 108
(51+57)/2 = 54
Half of 51/57 = 51/(57*2) = 51/114 = 0.4474 approx.
The odd numbers between 14 and 20 are 15, 17, and 19. To find their sum, you add them together: 15 + 17 + 19 = 51. Therefore, the sum of the odd numbers between 14 and 20 is 51.
The odd numbers between these values are 49, 51, 53, 55, 57 and 59.

52+54+56 = 162
(51+57)/2 = 54
The integers are 51, 53, 55 and 57.
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.
Half of 51/57 = 51/(57*2) = 51/114 = 0.4474 approx.
51 54 57
The numbers are 51, 53, 55 and 57.
The odd numbers between 14 and 20 are 15, 17, and 19. To find their sum, you add them together: 15 + 17 + 19 = 51. Therefore, the sum of the odd numbers between 14 and 20 is 51.
Let the lowest odd number equal x, thus: x + x + 2 + x + 4 = 57 3x + 6 = 57 3x = 57 - 6 3x = 51 x = 51/3 x = 17 The three numbers are therefore 17, 19 and 21.
The odd numbers between these values are 49, 51, 53, 55, 57 and 59.
The sum of 57 is 57 itself. In mathematical terms, the sum refers to the result of adding two or more numbers together. Therefore, when you add 57 to another number or to itself, the sum will be the total value of those numbers, which in this case is 57.
