    n + 1 = would be 1 + 1, 2+1, 3+1, 4+1 etc

    So how would I solve this for the first 4 terms? I'm sure this is probably something simple, but I still don't understand, sorry

    \[t _{0}=-3\]and\[t _{1}=17\] looks like ap to me with d=20

    then you just add 20 to get t_2 and so on

    it wants you to find something that starts with 17 and ends with -3

    A will never touch -3, it will brush pass -3 but not land on -3

    So... D or C? Which one is correct though?

    you might need to re-read the questions, for D : \[t _{11}=17+(11-1)(-2) = -3\] for C because its a -1 step you will eventually get to -3 no matter what.

    Very common, especially with online classes, which is what this is for. It's just easier to grade I suppose.

    At least with multiple choice the chances of getting it wrong are narrower, so I guess we're lucky. And thankyou for your help!

    What is the circled part? Are you sure you copied the problem correctly? We see t1 = 17. That means the first term is 17. I don't see an equal sign in the circled expression, so I don't know what pattern to follow to find any other term. |dw:1438493213005:dw|
