A number pattern that increases by 5 has a constant difference: each term is found by adding 5 to the preceding term, such as 20, 25, 30, 35. The learner extends such sequences within familiar numbers to 100, using a number line or hundred chart to track equal jumps and noticing that the ones digit alternates between 0 and 5; general rules for larger numbers or formal algebraic notation are not included.
A number pattern that goes up by means add each time.
Look at this pattern:
Start with and add :
So the completed pattern is:
You can also use a number line. Start at and make equal jumps of :
Check your work: the ones digits go . Each number is exactly more than the number before it.
