Always-sometimes-never? When n is a positive whole number, which of these expressions are: Always a multiple of 3 Sometimes a multiple of 3 Never a multiple of 3

2
Always-sometimes-never? 3n + 1 2n + 3 3n + 3 3n – 5 2n + 1 5n – 3

3
Always-sometimes-never? Which of these statements are always -sometimes – never true? 3a + 1 = 3(a + 1) 5(2p + 6) = 10(p + 3) r 2 > 2r 2s + 1 = 2s - 1

If a = 1 2a + 1a2a2 (a + 1) 2 2(a + 1)3a + 1100 – a 2 10 - a10a(a+1)(a–1)

5
If a = 10 2a + 1a2a2 (a + 1) 2 2(a + 1)3a + 1100 – a 2 10 - a10a(a+1)(a–1)

6
If a = -1 2a + 1a2a2 (a + 1) 2 2(a + 1)3a + 1100 – a 2 10 - a10a(a+1)(a–1)
