Question

Please help me on #8 I don’t know what I did wrong

Answer 1

Okay, here we have this:

Considering the provided sequence, we obtain that:

Since the function does not have a constant difference or ratio, it is not an arithmetic or geometric sequence, then: All the terms in odd position are 6, and the terms in even position are equal to 8, this can be represented as follows:

`a_n=\begin{cases}6ifn(\mod )2==1 \\ 8if\text{ n(mod)2==0}\end{cases}\text{ }`
