He is wrong. You first need to put it in order before getting the middle. Like so:
22, 36, 48, 60, 84
Now cross out 22, then 84, and so on till you're left with one number (the middle number)
THE ANSWER IS 48
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
hello : here is an solution 
Leading coefficient :  1  , 0  , -3  ,0  , -3   because : y = 1x4+0x^3 - 3x2+0x - 3
Degree: 4
