Study the given pattern carefully and select the number from among the given options that can replace the question mark (?) in it.
(7, 9, 130), (11, 9, ?), (16, 8, 320)
In each set third number = $$\left(first\ number\right)^2+\left(\sec ond\ number\right)^2$$
(7, 9, 130)
third number = $$\left(7\right)^2+\left(9\right)^2$$
= $$49+81$$
= 130
(16, 8, 320)
third number = $$\left(16\right)^2+\left(8\right)^2$$
= $$256+64$$
= 320
(11, 9, ?)
third number = $$\left(first\ number\right)^2+\left(\sec ond\ number\right)^2$$
= $$\left(11\right)^2+\left(9\right)^2$$
= $$121+81$$
= 202
Hence 202 will come in place of the question mark.
