- 1.Write down the first four terms of the sequence with nth term 6n − 5.
- 2.The nth term of a sequence is 4n − 3. Work out the 7th term of the sequence.
- 3.A geometric sequence has first term 5, and each term after that is 3 times the term before it. Work out the first term of the sequence that is greater than 1000.
- 4.A company's profit was £2000 in its first year. Each following year, the profit increases by £800. Work out the first year in which the profit is more than £7000.
- 5.The nth term of a sequence is 2n² + 1. Work out the 4th term of the sequence.
- 6.A geometric sequence starts at 3, and each term after that is found by multiplying the term before it by 2. Write down the first four terms.
- 7.Matchsticks are laid out as a row of squares, with each new square sharing a side with the square before it. The first square uses 4 matchsticks and every extra square uses 3 more. Work out how many matchsticks a row of 4 squares uses.
- 8.A sequence begins at 60, and each term after that is found by subtracting 7 from the term before it. Work out the 5th term of the sequence.
- 9.A sequence has the position-to-term rule 5n − 2, where n is the position number. Which of these is a term in the sequence?
- 10.The nth term of a sequence is n² + 3. Work out the first term of the sequence that is greater than 50.
- 11.A sequence begins at 7. Each term after the first is found by adding 6 to the term before it. Work out the 6th term of the sequence.
- 12.A geometric sequence starts at 4, and each term after that is found by multiplying the term before it by 3. Write down the first four terms of the sequence.
- 13.The nth term of a sequence is 2n − 1. Work out the 6th term of the sequence.
- 14.Here are the first five terms of an arithmetic sequence: 2, 5, 8, 11, 14. Work out the 8th term.
- 15.A plant is 4 cm tall in week 1. Each week after that, its height increases by 5 cm. Work out the first week in which the plant is taller than 30 cm.
