A recursive formula requires that you know the previous term in order to find the next one- that is, you need to know term n-1 in order to find term n. The formula itself will have " a sub n - 1." An explicit formula only has "a sub n." You can find any term without having to know any terms around it. If you're asked to determine whether a formula is recursive or explicit, look to see if you're given the first term and " a sub n - 1" (recursive) or just " a sub 1" (explicit.)
