Sum of numbers.

A summation has 4 key parts: the upper bound (the highest value the index variable will reach), index variable (variable that will change in each term of the summation), the lower bound (lowest value of the index value - the one it starts at), and an expression.

It is equal to n divided by 2 times the sum of twice the first term – ‘a’ and the product of the difference between second and first term-‘d’ also known as common difference, and (n-1), where n is numbers of terms to be added. The nth partial sum of the series is the triangular number = = (+), which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum. These non-fixed indices allow us to find rules for evaluating some important sums. Proof by (Weak) Induction. When we count with natural or counting numbers (frequently denoted ), we begin with one, then keep adding one unit at a time to get the next natural number. We then add one to that result to get the next natural number, and …If you have two arrays with different lengths then here is how you can sum them up. var array1 = [1,2,3,4,9]; var array2 = [5,6,7,8]; sum = [6,8,10,12,9]; We can start a new loop and then check if the index exists in the array if not then assign it to 0.
