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 sum of the first 10 counting numbers (1-10) is 51.
Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550

51
The sum of the first 10 counting numbers (1-10) is 51.
50 and 52 are the even numbers in this range, the odd numbers will be all the others, which is just the number 51.
A sum has to include two or more numbers in the calculation.
Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550
51 + 57 = 108
I believe here are 51 such numbers.
16 and 35
The sum of the four given numbers is -13.
