Answer:

4  5  9

11  6  1

3  7  8

Step-by-step 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

Answer:

+5

Step-by-step 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
