The common difference is the difference between consecutive terms in the sequence. In this case, we don't have enough information to determine the common difference based on the given recursive formula.
The initial term, a1, is given as 5.
The recursive formula is solving for the term an, which represents any term in the sequence.
To determine what should be in place of the n-1, we need more information or context. The given equation a4 = an-1 + 2 suggests that we are trying to find the value of the 4th term (a4) using the value of the previous term (an-1).
Given the Recursive Formula:
a1 = 5
a4 = an-1 + 2
What is the common difference?
What is the initial term?
What term is this formula solving for?
what should be in place of the n-1?
