Web1 aug. 2024 · Solution 2 Hint: To do it with induction, you have for n = 1, n 4 − 4 n 2 = − 3, which is divisible by 3 as you say. So assume k 4 − 4 k 2 = 3 p for some p. You want to prove ( k + 1) 4 − 4 ( k + 1) 2 = 3 q for some q. So expand it, insert the 3 p you know about, and you should find the rest is divisible by 3. emblehope
