Question
What will come in place of question mark [?] following
the same pattern as given below?Solution
The logic followed here is as follows. The sum of the squares of all the number that are given around the triangle is written in the middle of the triangle. In triangle 1 [7, 12, 17, 630] → 7² + 12² + 17² = 49 + 144 + 289 = 482 Similarly, in triangle 2 [11, 15, 13, ?] → 11² + 15² + 13² = 121 + 225 + 169 = 515
