Number Patterns practice questions

Secondary 1 topics, the foundation the O-Level Mathematics 4052 syllabus builds on. Every question below has a full worked solution.

When a student gets a question wrong in Math Amigo, it does not show the answer straight away. It reads the working, identifies the step that went wrong, and asks a question that points at the correction. The worked solution is there once a genuine attempt has been made.

What this topic covers

Worked examples

Example 1

Find the next term: 92,85,78,71,64,…92, 85, 78, 71, 64, \ldots
Show the worked solution
  • $92, 85, 78, 71, 64, \ldots$
  • $\text{Common difference} = 85 - 92 = -7$
  • $\text{Next term} = 64 - 7$
  • $= 57$

Answer: 5757

Example 2

Given Tn=3n−1T_n = 3n - 1, find T1×T2T_{1} \times T_{2}.
Show the worked solution
  • $T_{1} = 3(1) - 1 = 2$
  • $T_{2} = 3(2) - 1 = 5$
  • $T_{1} \times T_{2} = 2 \times 5$
  • $= 10$

Answer: 1010

Example 3

Find TnT_n for the sequence 6,13,20,27,34,…6, 13, 20, 27, 34, \ldots
Show the worked solution
  • $6, 13, 20, 27, 34, \ldots$
  • $\text{Common difference } d = 13 - 6 = 7$
  • $T_n = 7n + c$
  • $T_0 = T_1 - d = 6 - 7 = -1$
  • $T_n = 7n - 1$

Answer: 7n−17n-1

Questions parents ask

Is it really free?

The free plan is permanent and does not ask for a card. It has daily limits on the AI feedback, and the paid plans lift them.

Which syllabus does this follow?

O-Level Mathematics (4052), for Singapore secondary students. Math Amigo covers Secondary 1 to 4, both O-Level Mathematics and Additional Mathematics.

Will it just show my child the answer?

No. On a wrong answer it looks at the working, points to the step that went wrong, and asks a question that helps the student find the correction. The full worked solution is available after a genuine attempt.
