Hi guys,
I need help with the question attached.
Can't find the pattern...
Thank you.
The pattern is this:
You add the sides of the triangle and multiply the sum by -4 to get the inside number of the triangle.
Proof:
1st Triangle = 2-3-5 = -6 x -4 = 24
2nd Triangle = 6-1-2 = 3 x -4 = -12
3rd Triangle = 8-2-10 = -4 x -4 = 16
4th Triangle = 7 + 5 -4 = 8 x -4 = -32
They all check out.
Now we just apply this to the new triangles to determine the new numbers:
1st Triangle = 4 - 6 - 11 = -13 x -4 = 52
2nd Triangle = 11 - 3 - 8 = 0 x -4 = 0
3rd Triangle = 12 - 4 - 2 = 6 x -4 = -24
4th Triangle = 5 + 9 - 6 = 8 x -4 = -32
Thus 52, 0 , -24, and -32 are your new numbers.
