Question

Complete the Magic Square.

Answer 1

+5

Explanation:

So you can see the 5 pattern, so you add 9+5= 14 which goes in the middle square and 14+5=18 in the left square

Now between 18 and 11 it is 7 so you subtract 7 which equals 4 then - 5= -1 then -5= -6

Answer 2

4 5 9

11 6 1

3 7 8

Explanation:

In a magic square, all rows, columns, and diagonals have the same sum.

Let's call the cells a - i this way:

a b c

d e f

g h i

Now lets's fill in what we have:

a b 9

11 6 1

g h i

2nd row: 11 + 6 + 1 = 18

3rd column: 9 + 1 + i = 18; i = 8

a b 9

11 6 1

g h 8

Main diagonal: a + 6 + 8 = 18; a = 4

4 b 9

11 6 1

g h 8

1st row: 4 + b + 9 = 18; b = 5

4 5 9

11 6 1

g h 8

1st column: 4 + 11 + g = 18; g = 3

4 5 9

11 6 1

3 h 8

2nd column: 5 + 6 + h = 18; h = 7

4 5 9

11 6 1

3 7 8
