Question

answer the question plz all of you

Answer 1

11^2-1=120
7^2-2^2=45
5^2-3^2=16

Answer 2

The correct answer is 16
See the columns upside down..

The last box =
${second \: box}^{2} \: - \: {first \: box}^{2}$
This is the general trend ...
In 1st column
(11)^2 - (1)^2 = 120


In second box
(7)^2 - (2)^2 = 45

Simillarly in 3rd box (5)^2 - (3)^2 = 16

Hope it helped
