Show answers and working
1. 19, 23
The difference is 4. 15 + 4 = 19, then 23.
2. 22, 26
The difference is 4. 18 + 4 = 22, then 26.
3. 29, 32
The difference is 3. 26 + 3 = 29, then 32.
4. 28, 34
The difference is 6. 22 + 6 = 28, then 34.
5. -2n + 12
Common difference -2, so start with -2n. -2 × 1 = -2; the first term is 10, so adjust by 12. nth term = -2n + 12
6. 4n + 7
Common difference 4, so start with 4n. 4 × 1 = 4; the first term is 11, so adjust by 7. nth term = 4n + 7
7. -4n + 23
Common difference -4, so start with -4n. -4 × 1 = -4; the first term is 19, so adjust by 23. nth term = -4n + 23
8. -5n + 17
Common difference -5, so start with -5n. -5 × 1 = -5; the first term is 12, so adjust by 17. nth term = -5n + 17
9. -4n + 12; 50th term = -188
Common difference -4, so start with -4n. -4 × 1 = -4; the first term is 8, so adjust by 12. nth term = -4n + 12
10. 5n + 6; 50th term = 256
Common difference 5, so start with 5n. 5 × 1 = 5; the first term is 11, so adjust by 6. nth term = 5n + 6
11. -1n + 4; 50th term = -46
Common difference -1, so start with -1n. -1 × 1 = -1; the first term is 3, so adjust by 4. nth term = -1n + 4
12. -4n + 15; 50th term = -185
Common difference -4, so start with -4n. -4 × 1 = -4; the first term is 11, so adjust by 15. nth term = -4n + 15
Worked examples
Find the next two terms: 17, 26, 35, 44, …
- The difference is 9.
- 44 + 9 = 53, then 62.
- Answer: 53, 62
Find the nth term of 18, 27, 36, 45, …
- Common difference 9, so start with 9n.
- 9 × 1 = 9; the first term is 18, so adjust by 9.
- nth term = 9n + 9
- Answer: 9n + 9
Find the nth term of 14, 17, 20, 23, … and the 50th term.
- Common difference 3, so start with 3n.
- 3 × 1 = 3; the first term is 14, so adjust by 11.
- nth term = 3n + 11
- Answer: 3n + 11; 50th term = 161

Common mistakes
What learners typically get wrong, and how to fix it.
Writes n + 3 for a sequence going up in 3s.
Correction: Going up in 3s means 3n.
Forgets to adjust for the first term.
Correction: Compare 3n with the actual sequence.
Teacher tips
- · Line the sequence up under the times table to find the adjustment.
Parent tips
- · Track weekly savings and predict week 10.
Real-life applications
- · Taxi fares, saving the same amount each week.
