Find the missing number in Following table (In the middle row, middle number is 18 and not 28.)

Solution

In each column, the sum of square root of first and third number is equal to the middle number.

Eg : $$\sqrt{49}+\sqrt{100}=7+10=17$$

and $$\sqrt{169}+\sqrt{25}=13+5=18$$

Similarly, $$\sqrt{196}+\sqrt{144}=14+12=26$$

Thus, missing term = 26
