    What type of sequence is it? Arithmetic or geometric?

    Okay. So there are two methods to arithmetic sequences. The explicit and recursive but we'll be focusing on explicit since that's what they want. Do you know the formula for it?

    I think I wouldn't be sure is an-a+(n-1)d

    Pretty much. \[a _{n} = a _{1} + (n-1)d\] Where a1 is the 1st term. n = position of term d = common difference an = desired term of sequence
