Answer:

  • 12, 13, 15 and 19

----------------

The first term is given, 12.

Find the next three terms using the given formula:

  • a₂ = 2(a₁) - 11 = 2(12) - 11 = 24 - 11 = 13
  • a₃ = 2(a₂) - 11 = 2(13) - 11 = 26 - 11 = 15
  • a₄ = 2(a₃) - 11 = 2(15) - 11 = 30 - 11 = 19

So the first 4 terms are 12, 13, 15 and 19.
