Yes, the statement 5n + 7 divisible by 4 is provable by complete induction. Complete induction involves proving a statement for all natural numbers, starting from a base case and then proving the statement for an arbitrary natural number assuming it holds for all smaller natural numbers. In this case, we can use complete induction to prove that 5n + 7 is divisible by 4 for all natural numbers n. **
