Triangle math puzzle

Triangle math puzzle with answer

Answer:

Based on the pattern of the first two triangles, we can assume that the number in the center of the third triangle is the average of the numbers on the corners.

Therefore, in the third triangle where the sides are all 5, the number in the center would be:

(5 + 5 + 5) / 3 = 5

So the answer of this triangle puzzle is 5.

What is the centre number of the 3rd triangle?

The three corners of the 1st triangle have three numbers, 5, 22, 1. There is 17 in centre.

We get,

22-5×1 =17

There are three numbers, 4,53,3 at three corners of the 2nd triangle. There is 41 in centre.

We get, 53 -4×3=41

So, the centre number of the 3rd triangle will be 55-5×5=30

Answer : 30
