Can someone help me with this

read the textbook man

Which questions?

I won't tell you the answers but I'll help out:

Arithmetic is when you add something each time, geometric is when you multiply. So the first sequence in question 2 is geometric because you're multiplying by 2 each time, or x(n) = 3 * 2^(n-1)

Similarly the third sequence is arithmetic because you add -7 each time, so your expression will begin with -7, then you just add whatever brings you to the first term. In this case it's x(n) = -7n + 8

Now you do the rest. Questions 3-5, it's pretty much in the textbook as anon said.

I really shouldn't, but its 4chan. Photomath app. They haven't implemented handwritten yet, but text is fine. Does calc.
