What value of k causes the terms 6, 4k, 26 to form an arithmetic sequence?

There are 3 values given,

Find the difference between the first and last values:

26 - 6 = 20

Divide that by 2:

20 / 2 = 10

The difference between each number needs to be 10, so adding 10 to the first number would be 6 +10 = 16

Now 4k = 16

Divide both sides by 4:

k = 16/4

k = 4
