If the median of five consecutive even integers is 20, what is the value of the smallest integer?
IceJOKER [234]

Answer:

16

Step-by-step explanation:

Median means the middle number. So you can look at it like this:

<em>a,b,</em> 20, <em>c,d</em>

Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.

This should be your answer:

16, 18, 20, 22, 24

Consecutive, and even.
