The question, in short

A sequence has nth term 5 − 2n. Find its 6th term and identify the largest value the sequence can take.

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

Part (a) · 1 mark

Substitute n = 6 into 5 − 2n to work out the 6th term.

  1. 1n = 6: 5 − 2 × 6
  2. 2= −7

Answer−7

Part (b) · 1 mark
