Answer
195
Explanation
Solution
So, this question will be done by this logic,
Square of the sum of the number at the corner - 1 = Number at the center.
So, according to this,
(2 + 6 + 2 + 3)2 -1 = (13)2 -1 = 169 -1 = 168
(1 + 2 + 3 + 5)2 -1 = (11)2 -1 = 121 - 1 = 120
(2 + 3 + 4 + 5)2 - 1 = (14)2 -1 = 196 - 1 = 195
So, the number in the middle for third figure will be 195
The correct option is (B): 195
