(n)( n+1)/2 where n = 50. (50 x 51)/2 = 2,525
What is the sum of the interior angles of a polygon with 53 sides?
(n - 2)x180 where n = number of sides so ... 51 x 180
What is the sum of the numbers 1-50?
51
What is the sum expression for the sum of n and 5?
The sum of n and 5 is n+ 5
What is the sum between 51 and 57?

The sum of 42 and a number n is equal to 51?
n=9. Because n+42=51. Subtract 42 from both sides and n=9
What is the sum of the numbers from 1 to 50?
Sum of first n integers = n/2(n+1), in this case 25 x 51 = 1275
How would you find the sum of the first 50 even numbers?
Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550
What is the sum of all the natural numbers from 1 to 50?
(n)( n+1)/2 where n = 50. (50 x 51)/2 = 2,525
What is the sum of the interior angles of a polygon with 53 sides?
(n - 2)x180 where n = number of sides so ... 51 x 180
What is the sum of the numbers 1-50?
51
What is the sum of all the numbers from 51 to 150?
This is an arithmetic series, so we use the formula S=n/2 (a+l) when n is the number of terms, a is the first number and l the last. S = 100/2 (51 + 150) =50 (201) = 10050
The sum of 38 and 51?
38+51 = 89
Write a c program to print the sum of even numbers from 300 to 400?
int n, N;N = some even numberfor (n=2; n
What is the sum expression for the sum of n and 5?
The sum of n and 5 is n+ 5
What is the sum of the first 102 counting numbers?
If you want to sum up numbers 1 to N, you can do it this way. Sum = (N+1)*(N/2).The reason this works: say you want to sum up 1 through 10. You have 10+1, 9+2, ..., 6+5. Each of these equals 11 [N+1]. You added 11 five times (N/2). Sum of 1 to 102 = (102+1)*(102/2) = 103*51 = 5253. You can check it by summing up the numbers with a spreadsheet.
The sum of 51 to 150?
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.
