Question

A pattern is made using matchsticks. What is the number of matchsticks needed to create the next member in the pattern? [3 MARKS]

Answer 1

Visualisation of question: 1 Mark
Identifying the pattern: 1 Mark
Solution: 1 Mark

Number of sticks used for the first member = 6

Number of sticks used for the second member = 6 + 5 = 11

Number of sticks used for the third member = 6 + 5 + 5 = 16

Therefore, number of sticks required for the fourth member = 16 + 5 = 21
