I presume you mean



If you work out the first 12 terms, you will notice a pattern:



Yes, indeed, the set of values repeats every six terms. Using integer division, divide 1485 by 6 and note the remainder. Count the number of terms in the list up to the remainder you just obtained, and that will be the value of
