Across
  1. 2. Means going up or increasing. For example, the numbers 1, 2, 3, 4 are ascending.
  2. 5. Something that forms a straight line. In maths, when we talk about a linear pattern, it means the numbers go up or down by the same amount each time, in a straight line.
  3. 6. Means going down or decreasing. For example, the numbers 10, 9, 8, 7 are descending.
  4. 8. A list of numbers that follow a special pattern or order. E.g. 2, 4, 6 (each number is 2 more than the one before it)
  5. 9. The number that is added or subtracted each time to get from one term to the next in a sequence. For example, in the sequence 3, 6, 9, 12, the common difference is 3.
  6. 10. Tells you how to get from one number in a sequence to the next. E.g. a rule could be "add 3"
Down
  1. 1. A sequence where each number is the same distance away from the next. The numbers go up or down by the same amount each time, forming a straight line when you plot them. For example, 5, 10, 15, 20 is a linear sequence because we add 5 each time.
  2. 3. Tells you what number is in a certain place in the sequence. For example, in the sequence 2, 4, 6, 8, the position-to-term rule is "multiply the position by 2."
  3. 4. How much one number is greater or less than another.
  4. 7. Any number in a sequence or equation. For example, in the sequence 3, 6, 9, 12, the terms are 3, 6, 9, and 12.
