I still remember my brother taught me this simple math....
First, add 1 with the last number. So, 50 + 1 = 51
Then divide the last number with 2. So, 50/2 = 25
So, 51 X 25 = 1275

They total 650. * * * * * It is 2550.
49+50+51=150 General rule for this kind of question: divide the number you're trying to obtain (150) by the number of integers you're allowed (3), and then simply add one and subtract one until you have the specified number of integers.
45
sum of n natural number is n(n+1)/2 first 50 number sum is 50(50+1)/2 = 1275
Sum of first n integers = n/2(n+1), in this case 25 x 51 = 1275
810. All of the integers from -30 to30 cancel each other out by adding a negative to a positive. Then all you need to do is add the integers from 31 to 50. (31 + 32 + ....+50)
It's easy to work it out yourself.... Multiply 100 by 49, add 50, add 100 - and you have your answer !
-15
5 & 10
The integers are 49 and 50.
1275
no solultion!
It can be.
50, 51, 52
If you write down all of the integers between the two numbers, your sum is equivalent to 5,659.
They total 650. * * * * * It is 2550.
50 + 51 + 52 = 153
