The Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic Sequence Formula: an = a1 +d(n −1) a n = a 1 + d (n - 1) Geometric Sequence Formula: an = a1rn−1 a n = a 1 r n - 1.
Find the sum of the first 50 odd numbers: 50. [tex]\sum\ [/tex] 2n-1. n=1. Homework Equations. Summation problem. The Attempt at a Solution. As I said, I've only solved this specific type of summation problem using a calculator, but I know how to do regular summation problems, for instance: 6. [tex]\sum\ [/tex] 2n-1. n=1. 2 (1)-1 = 1. 2 (2)-1 = 3.
31 Ιουλ 2023 · From the above evaluation, we can prove that the formula to find the sum of the first n odd numbers is n x n or n 2 . For instance, if we put n = 21, then we have 21 x 21 = 441, which is equal to the sum of the first 21 odd numbers.
