Explicit formulas can be used to determine the number of terms in a finite arithmetic sequence. We need to find the common difference, and then determine how many times the common difference must be added to the first term to obtain the final term of the sequence. How To:...
Sum of the Terms of an Arithmetic Sequence The sum of the first n terms of an arithmetic sequence is given by Sn=n⋅a1+an2Answer and Explanation: We are given that the sum of 6 consecutive integers is 519. Let x be the first term in the sequence. ...
There are also patterns, between the terms of two or more arithmetic sequences. For example, Both sequences start at 0. If you multiply the left column by 3, you get the terms in the right column. This is because using the rule +9 is three times more than the rule +3. Step-by...
