The series starts out with 324 which is 18^2
The next number is 256 which is 16^2
The next number is 196 which is 14^2
The final given number is 144 which is 12^2

So the next number in line is 100 which is 10^2
The pattern is even numbers that are squared. The even numbers are going down so that the next number down would be 64
