Answer and step-by-step explanation:
To identify what kind of sequence that is, let's find the common difference(if there is) by subtracting each term by the previous term.
3/4, 1, 5/4, 3/2, ...
1 - 3/4 = 1/4
5/4 - 1 = 1/4
3/2 - 5/4 = 1/4
*Observe that they all have the same answers and this is called the common difference.
*If a sequence has a common difference, it is called an arithmetic sequence.
The given sequence is an arithmetic sequence.
