Answer:

When you see the table you will be able to make out the connection between the numbers.

In the first 2 columns you will see that the last row is the sum of the second and third row.

i.e. 15 + 5 = 30 &

7 + 13 = 20

Also 1st row is (R2)^2 + 1 where R2 is second row.

i.e. 5^2 + 1 = 26 &

7^2 + 1 = 50.

So we can find the missing number N as;

N + 9 = 20;

N = 20 – 9 = 11

Also

122 – 1 = 121 = 11^2

So the missing number is 11
