Definition
Consecutive numbers
Consecutive numbers are neighbours in an ordered number set, with none from that set skipped.
What it means
Think of next-door neighbours on the number list. For whole numbers or integers, move one step each time: 47, 48, 49. If a different set is named, use that set's order: 8 and 10 are consecutive even numbers because no even number lies between them.
Remember it
Next-door neighbours on the stated number list.
Example
47, 48, and 49 are consecutive whole numbers because each is 1 more than the previous number. The pair 47 and 49 is not consecutive in the whole numbers because 48 is skipped.
Watch for
The set must be stated when it changes the step. Eight and ten are not consecutive whole numbers, but they are consecutive even numbers.
Common mix-up
A pattern such as 3, 6, 9 is a sequence, but its terms are not consecutive whole numbers because numbers are skipped.
Exact meaning
Consecutive numbers are neighbouring members of a stated ordered number set, with no member of that set between them.
