If the common difference between the terms of the sequence is -15, what term follows the term that has the value 15?
The term following 15, for an arithmetic progression with a common difference of -15 would be 0.
Briefly, an arithmetic progression is a series of numbers which start with a base value and progresses with each succeeding term, differing from the preceding term by a common difference.
A generic series will be:
#a#is the 1st term #d#is the common difference #a+(n-1)*d#is the #n^(th)#term of the sequence
So, for a series with 15 as 1st term and common difference -15, the 2nd term would be,
If 15 is any term along the series and not necessarily the 1st term, then the next term would again be,
