Answer:
You add by 5, then 15, then 45 and so on
Step-by-step explanation:
First, you add 5, then you add 15, then you add 45 and so on. You are multiplying 3 and 5 every-time. I don't really know how to explain it but ya.
To get from 3 to 8, add 5. To get from 8 to 23, add 15. You're multiplying by 3 for every number. (I'm super bad at explaining)
Answer: Add the number previously added multiplied by 3;
+3x, where x is the number that was added previously
Step-by-step explanation:
3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.
