Show answers and working
1. 51, 59
The difference is 8. 43 + 8 = 51, then 59.
2. 13, 16
The difference is 3. 10 + 3 = 13, then 16.
3. 24, 27
The difference is 3. 21 + 3 = 24, then 27.
4. 37, 42
The difference is 5. 32 + 5 = 37, then 42.
5. 3n − 1
Common difference 3, so start with 3n. 3 × 1 = 3; the first term is 2, so adjust by -1. nth term = 3n − 1
6. -4n + 24
Common difference -4, so start with -4n. -4 × 1 = -4; the first term is 20, so adjust by 24. nth term = -4n + 24
7. 9n − 6
Common difference 9, so start with 9n. 9 × 1 = 9; the first term is 3, so adjust by -6. nth term = 9n − 6
8. 9n − 4
Common difference 9, so start with 9n. 9 × 1 = 9; the first term is 5, so adjust by -4. nth term = 9n − 4
9. 2n + 2; 50th term = 102
Common difference 2, so start with 2n. 2 × 1 = 2; the first term is 4, so adjust by 2. nth term = 2n + 2
10. 1n + 18; 50th term = 68
Common difference 1, so start with 1n. 1 × 1 = 1; the first term is 19, so adjust by 18. nth term = 1n + 18
11. 7n − 4; 50th term = 346
Common difference 7, so start with 7n. 7 × 1 = 7; the first term is 3, so adjust by -4. nth term = 7n − 4
12. -4n + 14; 50th term = -186
Common difference -4, so start with -4n. -4 × 1 = -4; the first term is 10, so adjust by 14. nth term = -4n + 14
Worked examples
Find the next two terms: 3, 10, 17, 24, …
- The difference is 7.
- 24 + 7 = 31, then 38.
- Answer: 31, 38
Find the nth term of 11, 6, 1, -4, …
- Common difference -5, so start with -5n.
- -5 × 1 = -5; the first term is 11, so adjust by 16.
- nth term = -5n + 16
- Answer: -5n + 16
Find the nth term of 12, 6, 0, -6, … and the 50th term.
- Common difference -6, so start with -6n.
- -6 × 1 = -6; the first term is 12, so adjust by 18.
- nth term = -6n + 18
- Answer: -6n + 18; 50th term = -282

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.
