Apr 20 2020 When trying to determine what kind of sequence it is first test for a common difference and then test for a common ratio.
So the explicit form of our arithmetic sequence is. Jul 10 2020 In an arithmetic sequence the difference an addition or subtraction between any two consecutive terms is a constant. In that case substituting it back into r 1 d a 1 gives r 2. To find the common difference subtract a term from the one before it.
