Answer:
12
Step-by-step explanation:
√9 = 3 and √16 = 4
3 + 4 = 7
There is the same relationship in the second and third set of numbers.

Answer:
12.
Step-by-step explanation:
We have been given format of different numbers. We are asked to find the missing value for our given format.
[tex]9,16=7[/tex]
Taking square root of 9 and 16 we will get,
[tex]\sqrt{9}=3[/tex]
[tex]\sqrt{16}=4[/tex]
[tex]3+4=7[/tex]
Similarly, we can see that by taking the square root of all the on the left side of equation and adding them we get right side of equation.
[tex]\sqrt{4}=2[/tex]
[tex]\sqrt{36}=6[/tex]
[tex]2+6=8[/tex]
[tex]\sqrt{121}=11[/tex]
[tex]\sqrt{81}=9[/tex]
[tex]11+9=20[/tex]
Upon taking square root of 25 and 49 we will get,
[tex]\sqrt{25}=5[/tex]
[tex]\sqrt{49}=7[/tex]
[tex]5+7=12[/tex]
Therefore, the missing number of our given sequence is 12.
