Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts
A recursive formula requires that you know the previous term in order to find the next one that is, you need to know term n1 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.)
