  1. Objective Finding the nth term of a quadratic sequence

  2. n - n + 2 2 2 4 8 14 22 2 4 6 8 2 2 2

  3. 2n - 2n - 3 2 -3 1 9 21 37 4 8 12 16 4 4 4

  4. an + bn + c 2 a+b+c 4a+2b+c 9a+3b+c 5a + b 3a + b 2a Copy this down and learn it

  5. a+b+c 4a+2b+c 9a+3b+c 3a + b 5a + b 2a an + bn + c 2 3 4 11 24 1 7 13 6 6

  6. an + bn + c 2 3 6 = 2a 1 6 1 = 3a + b a+b+c 3 = a + b + c 3a + b 2a

  7. b 2 2 + n - 8 3 a n c 8 + 6 = 2a a = 3 1 = 3a + b b = -8 3 = a + b + c c = 8

  8. Find the nth terms of these sequences 3 5 9 15 23 2 10 22 38 58 -1 3 10 20 33 50 40 31 23 16

  9. an + bn + c 2 a+b+c 4a+2b+c 9a+3b+c 5a + b 3a + b 2a

  10. A cubic sequence is given by 3 2 an + bn + cn + d Can you find the algebraic difference table for it?
