How many tiles will be needed for the next pattern? 16 We add on four tiles each time.This is a term-to-term rule. Sequences from practical contexts

3 © Boardworks Ltd of 25 © Boardworks Ltd of 5 A possible justification of this rule is that each shape has four arms each increasing by one tile in the next arrangement. The pattern gives us multiples of 4: 1 lot of 42 lots of 43 lots of 44 lots of 4 The n th term is 4 × n or 4 n. Justification: This follows because the 10 th term would be 10 lots of 4.
