  1. Learning objectives:To find the next terms in a sequence and to find the nth term of a sequence

  2. = 4 × 1 + 2 = 6 1st term 4n + 2 = 4 × 2 + 2 = 10 2nd term = 4 × 3 + 2 = 14 3rd term 4th term = 4 × 4 + 2 = 18 5th term = 4 × 5 + 2 = 22 6 10 14 18 22

  3. = 5 × 1 - 4 = 1 1st term 5n - 4 = 5 × 2 - 4 = 6 2nd term = 5 × 3 - 4 = 11 3rd term 4th term = 5 × 4 - 4 = 16 5th term = 5 × 5 - 4 = 21 1 6 11 16 21
