Question

Find the missing number in the same rule is followed in all the three figure 1815 11 30 2719 4539?

Answer 1

The value of missing number is 12.

Step-by-step explanation:

The missing figure are attached sheet:

To find, the missing number = ?

The pattern follow,

Upper number = $\sqrt{Product of downward numbers}$

In figure 1,

$8=\sqrt{4\times 16} =\sqrt{64} =8$

In figure 3,

$18=\sqrt{12\times 27} =\sqrt{324} =18$

Similarly,

In figure 3,

$? = \sqrt{18\times 8} =\sqrt{144} =12$

Hence, the value of missing number is 12.
