A sequence extending by 2 has a constant difference of 2: each term is two more than the preceding term, as in 6, 8, 10, 12. Within whole numbers to 100, this understanding supports continuing forward sequences, finding missing terms, and interpreting the pattern on a number line, including the distinction between sequences of odd and even numbers; negative numbers and formal algebraic rules are beyond this scope.
A number pattern that extends by gets more each time.
To continue the pattern:
Example:
Start with :
Then add again:
So the completed pattern is:
On a number line, you would hop forward spaces each time. Since the pattern starts with an even number, all the numbers in this pattern are even.
