Okay, here we have this:
Considering the provided sequence, we are going to find the fifth term, so we obtain the following:
To find the fifth term then we will substitute in the formula n=5, then we have:
[tex]\begin{gathered} a_n=4+(-1)" \\ a_6=4+(-1)^5 \\ a_6=4-1 \\ a_6=3 \end{gathered}[/tex]
Finally we obtain that the fifth term of the sequence is 3.
