sum of 150 what? first 150 numbers?
The sum is 150*151/2 = 11,325
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.
The numbers are -150 and -148.
25 and 6.
150 = 12 + 62 + 72 + 82
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
5625
169
The answer to that question is 49,50,51
10 and 15
100 + 49 + 1
