Answer: counting backwards, that should be -430
Step-by-step explanation: the 86th term counting backwards by 5
 
        
                    
             
        
        
        
It is 12/b: opposite/adjacent
        
                    
             
        
        
        
Because it is square, the distance from home to first base is the same as first base to second base.
Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.
Using the Pythagorean Theorem we can solve for the hypotenuse:
Let C = the hypotenuse:
90^2 + 90^2 = c^2
8100 + 8100 = c^2
16200 = c^2
c = √16200
c = 127.279 feet, round to 127 feet.
 
        
             
        
        
        
I think the answer would be $9.46 left as a tip for the waiter.
