Devin is skip counting. 5, 10, 15, 20, 25, 30, 35. What rule does this pattern follow?

he is skip counting by 5s

Step-by-step explanation:

the rule is +5

Step-by-step explanation: 5+5=10 10+5=15 15+5=20 20+5=25 25+5=30 30+5=35

Yes you are correct. The answer is -30

Explanation:

We are adding 2 negatives. So we effectively add the positive versions of each number, and then make the result negative.

You can think of it in terms of money: you start off 27 dollars in debt and then borrow 3 more dollars to be a total of 27+3 = 30 dollars in debt.

Or you can think of it like you're under the ocean. Writing -27 could mean you're 27 feet below sea level. Adding on -3, ie subtracting 3, would then move you down 3 feet to get to 27+3 = 30 feet below sea level.
