Look at the following series of numbers. kind of skip-counting does it show?  ... 28, 35, 42, 49\text { ... 28, 35, 42, } 49 \ldots

Studdy Solution

STEP 1

What is this asking? We're figuring out what number is being repeatedly added to get the next number in the sequence. Watch out! Don't just look at the first two numbers!
Make sure the pattern continues for *all* the numbers.

STEP 2

1. Find the difference between consecutive numbers.
2. Verify the pattern.

STEP 3

Alright, let's see!
We've got 3535 and 2828.
What's the difference?
We subtract the first number from the second number: 3528=735 - 28 = 7.
So, the difference is **77**.
Could we be skip-counting by 77?
Let's find out!

STEP 4

Now, let's check the next pair.
We have 4242 and 3535.
Subtracting the second number from the third number: 4235=742 - 35 = 7.
Awesome! We've got a difference of **77** again.

STEP 5

Let's make absolutely sure this pattern holds up!
We have 4949 and 4242.
The difference is 4942=749 - 42 = 7.
Boom! Another **77**.

STEP 6

Since the difference between each consecutive pair of numbers is consistently **77**, we can confidently say that this series shows skip-counting by 77!

STEP 7

The series of numbers shows skip-counting by 77.
