Which recursive formula can be used to represent the sequence 2,4,6,8,

represents the next number in the sequence

we can see that there is a common difference between each of the numbers:
4-2=2
6-4=2
8-6=2
10-8=2

represents the previous number in the sequence

this is the recursive formula for this equation

The last thing we need to do it double check the formula by plugging in numbers



we will skip to the last known number and check that one too
