Take note that the first term is 14 and we're adding 3 to each term to get the next term. So this tells us that and


So the general formula (which is an arithmetic sequence) becomes

where "n" starts at 0


Note: if you want to start at n=1, then simply subtract 3 from 14 (to scale back the terms) to get where "n" starts at 1.
