1 + 150 = 151
2 + 149 = 151
Therefore, there are 75 pairs each totalling 151
Therefore, the answer is
75 X 151 = 11325.

1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
The sum of all the odd numbers between 1 and 12000 is 36000000.
12^2+2^2+1^2+1^2 = 144 + 4 + 1 + 1 = 150.
The sum of all the odd numbers from 1 through 100 is 10,000
To find the sum of all numbers from 51 to 150, we can use the formula for the sum of an arithmetic series: (n/2)(first term + last term), where n is the number of terms. In this case, the first term is 51, the last term is 150, and the number of terms is 150 - 51 + 1 = 100. Plugging these values into the formula, we get (100/2)(51 + 150) = 50 * 201 = 10,050. Therefore, the sum of all numbers from 51 to 150 is 10,050.
