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.
It is: 810+50+150 = 1010
It is: 81050 plus 150 = 81200
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
I guess you mean: what two numbers sum to 31 and multiply together to get 150? 6 & 25 (6 + 25 = 31, 6 x 25 = 150)
Sum of 150's divisors = 372.
The sum of 150 and 150 is 300.
The sum is 150*151/2 = 11,325
