Each number is added by 3 so it's 17 20 23 26 29 32 35 38 41 and so on.
The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.

n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.
The possible values for n are 9, 10, 11, and 12.
The first one is negative six and the second one is positive six

➷ K - 2L = L - M
Subtract L from both sides:
K - 2L - L = -M
Add M to both sides:
K - 2L - L + M = 0
Add 2L to both sides:
K - L + M = 2L <== this is the answer
