Answer :
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
Answer:
k = 4.
Step-by-step explanation:
If it is arithmetic then the differences between consecutive terms will be equal, so:
4k - 6 = 26 - 4k
4k + 4k = 26 + 6
8k = 32
k = 32/8
k = 4.
