Question

What are the next to numbers in the sequence 1,5,3,10,5,15

Answer 1

Answer:

7, 20, 9, 25

Step-by-step explanation:

so basically we start off by seeing the 1,3 and 5, these are skipping two numbers each, we'll call this set a. After each set a number, there is a multiple of 5, so that's how the pattern goes on. I hope this helped.
