Answer: 7
Step-by-step explanation:
-if y is the width and the length of area k (see diagram), the difference between n and y is of 2 square sides, one at each side of y.
-therefore, assuming that n is a whole number and that there aren’t half squares, y must be a whole number too because, as previously said, n-y = 2 so y= n -2
-the only perfect square amongst the values for k you listed is 25, so taking n and y as whole numbers the only possible value for k is 25
-therefore y is 5 and n is 7 because n-y = 2 so y + 2 = n
1. controle if no numbers are missing and the numbers are in the right order
2. the formula is x-a so a=1
3. write everything out in the scheme
4. let the first number drop down
5. multiply the answers by a
6. add the number that are under each other
7. repeat 5 and 6 until to you're done
8. write down the equation
9. last number in the scheme is your residue, which means that you write it at the end, outside of the ()
