A worked example

Find the 16th term of the sequence 3, 11, 19, 27, … 123

  1. The common difference is 11 − 3 = 8
  2. The 16th term is the first term plus 15 jumps: 16 − 1 = 15, and 15 × 8 = 120
  3. 3 + 120 = 123

About these worksheets

Every problem is built backwards from its solution, so the answers are whole numbers and the answer key cannot be wrong. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.

Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
