Study the given pattern carefully and select the number from among the given options that can replace the question mark (?) in it.
(8, 4, 48), (3, 6, 36), (8, 6, ?)

Third number = $$4\times\left(first\ number + second\ number\right)$$

(8, 4, 48)

Third number = $$4\times\left(first\ number + second\ number\right)$$

= $$4\times\left(8+4\right)$$

= $$4\times12$$

= 48

(3, 6, 36)

Third number = $$4\times\left(first\ number + second\ number\right)$$

= $$4\times\left(3+6\right)$$

(8, 6, ?)

Third number = $$4\times\left(first\ number + second\ number\right)$$

= $$4\times\left(8+6\right)$$

= $$4\times14$$

= 56

So '56' will come in place of the question mark.
