Question

X 1 2 3 4
y 5 10 15 20


What's the constant?

Answer 1

x ---> 1

y ---> 5

Explanation:

We are given paired values for two variables x and y and we are to determine the constant number by which each term is increased such that they are in a proportional relationship.

For x, we have the following paired values:

`x: 1, 2, 3, 4`

So here the difference between each consecutive term is 1 so the constant is 1.

And for y, we have:

`y: 5, 10, 15, 20`

In this case, the difference between each consecutive term is 5 so the constant is 5.
