The question, in short

Sequence questions: continue 2, 5, 8, 11 by two more terms, and use the nth term n² + 3 to find the first three terms.

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 1 mark

Find the next two terms after 2, 5, 8, 11.

  1. 1The terms go up by 3 each time
  2. 211 + 3 = 14, 14 + 3 = 17

Answer14, 17

Part (b) · 2 marks

Using nth term n² + 3, find the first three terms.

  1. 1n = 1: 1² + 3 = 4
  2. 2n = 2: 2² + 3 = 7
  3. 3n = 3: 3² + 3 = 12

Answer4, 7, 12
