I can't seem to figure things out so I guess I am guessing again today. I am going to guess the number 7.

Is your number quiz guessing better than your football prediction guessing mate lol ;-)

Probably not. I am going out on a wild guess because I spent 5-10 minutes trying to solve it or find a pattern. Since I didn't find it, I am moving on after giving out a random number.

First count the external Triangles given in the image i.e. the edges ONE

Which external triangle? The external shape is a diamond or am I missing something mate? lol

Answer to today's puzzle is .....escaping me at the moment! I will I've it some thought and come back to you late!

Tricky one for sure.

Only thing I can think of that sort of makes sense:

3 x (2) = 6
4x (2) = 8
1 x (9) = 9

Following that it's:

2 x (4.5) = 9

Answer being 4.5

But the other numbers and the decimal don't make sense so doubt it's correct

The answer is "9/2"

Reason
Check the symmetry. Multiply the second digit with the number in bracket.

63 (2) 56 3 x 2 = 6
34 (2) 38 4 x 2 = 8
71 (9) 79 1 x 9 = 9
82 (?) 69 2 x 9/2 = 9

Hence the answer is 9/2
