1. Increases by 5 units
2. Any odd number multiplied by an even one yields an even number.
1) We can write out a sequence, an arithmetic one, to follow a pattern.
Note that the pattern here is the common difference between each term the first one is 5 and all the other ones increase by 5 units.
2) In this second case, we can pick "5" as well, but in this one, we'll make a Geometric Sequence for the following numbers will be written as the product of the prior term times 2:
Note that all the terms will be even numbers because any odd number multiplied by an even one yields another even number.
