Question

sum of an n term of an arithmetic sequence is 24 square - 4 write the algebraic form of this sequence​

Answer 1

Answer:

Sometimes, we want to add up the numbers in our sequence. For example, if our arithmetic sequence shows how many strawberries we are able to harvest each day, then adding up our sequence will tell us how many total strawberries we will have picked. To do this, we have a formula that will help us. The formula says that the sum of the first n terms of our arithmetic sequence is equal to n divided by 2 times the sum of twice the beginning term, a, and the product of d, the common difference, and n minus 1. The n stands for the number of terms we are adding together.

Arithmetic Sum

The part of this formula that we will use is the part after the equals sign. The part before the equals sign just tells you that you are going to add each term. What this first part does is gives you a way to calculate each term in your sequence and then to sum it up. But since we are looking for what this sum equals, we only need to concern ourselves with the part after the equ
