What is the formula of sum of series?
The sum of an arithmetic series is found by multiplying the number of terms times the average of the first and last terms. Example: 3 + 7 + 11 + 15 + ··· + 99 has a1 = 3 and d = 4. To find n, use the explicit formula for an arithmetic sequence.
What is the sum of sequence?

What is the sum of the squares of two numbers?
In number theory, the sum of two squares theorem relates the prime decomposition of any integer n > 1 to whether it can be written as a sum of two squares, such that n = a 2 + b 2 for some integers a, b. An integer greater than one can be written as a sum of two squares if and only if its prime decomposition contains no term p k, where prime
What is the formula for square numbers?
You can square a number in Excel with the power function, which is represented by the carat ^ symbol. Use the formula =N^2, in which N is either a number or the value of the cell you want to square. This formula can be used multiple times throughout a worksheet. Click inside a cell on your worksheet.
