RECURSIVE Patterns – Simple, ONE-STEP
We reviewed a simple increasing, recursive pattern.
(Remember, recursive means that we apply the same operation in the same way to every single term.
The first step is always to FIND THE GAP number between each term.
ALTERNATING Patterns
We reviewed alternating patterns — where two operations take turns being applied to the terms.
The first term experiences one operation (e.g. -3), and the second term experiences a different operation (e.g. -2) and so on in the same way. These two operations (-3 and -2) alternate with every other term.
The first step is always to FIND THE GAP number between each term. We noticed that the gap is alternating -3 and then -2.

RECURSIVE Patterns – TWO-STEP
Two operations are applied to EACH term in the same way. It is a recursive pattern (each term gets the same treatment).
To find the two-step pattern, we can infer the first operation by looking for a pattern in the gap number.
The first step is still to FIND THE GAP number between each term.
The second step is to see if there is a pattern with the gap number.
