There is no formula that will sum n even numbers without further qualifications: for example, n even numbers in a sequence.
The formula for finding the sum of all angles of a polygon is: N = number of sides (N-2)180 = The sum of all angles
n*(n+1)
The sum of the interior angles is (n-2)*180 degrees.
2n + 1 where n is an integer.
There is no formula that will sum n even numbers without further qualifications: for example, n even numbers in a sequence.
The formula for finding the sum of all angles of a polygon is: N = number of sides (N-2)180 = The sum of all angles
The formula is sum of interior angles = (n - 2)*pi radiansor (n - 2)*180 degrees.
n*(n+1)
The formula is (n-2)x180 over n =x
The formula for calculating the Gauss sum from 1 to 100 is n(n1)/2, where n is the number of terms in the sequence.

The formula for the sum of the first n terms of an arithmetic progression is Sn = n/2 * (a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term.
The formula is: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
The formula to find the sum of interior angles of a polygon is 180° × (n - 2), where n is the number of sides of the polygon.
The formula to find the sum of a geometric sequence is adding a + ar + ar2 + ar3 + ar4. The sum, to n terms, is given byS(n) = a*(1 - r^n)/(1 - r) or, equivalently, a*(r^n - 1)/(r - 1)
The sum of the interior angles is (n-2)*180 degrees.
