1. A chess player moves a knight from the location (3,2) to (5,1) on a chessboard.This means that
(3,2)→(5,1).
the translation rule is
(x,y)→(x+2,y-1) or in words 2 units right and 1 unit down.
2. If the player moves the knight from (5, 1) to (6, 3), then the translation is
(5,1)→(6,3)
and the rule is
(x,y)→(x+1,y+2).
This is translation 1 unit right and 2 units up.
Answer: 
<u>Step-by-step explanation:</u>

Let the four consecutive numbers be x, x+1, x+2, and x+3.
The sum of the four numbers is 54, therefore
x + (x+1) + (x+2) + (x+3) = 54
4x + 6 = 54
4x = 54 - 6 = 48
x = 12
Answer:
The four numbers are 12, 13, 14, and 15
