Notice the number of unshaded triangles in a pattern is the same as that of the shaded triangles in the previous pattern.

For example in pattern 3, the number of unshaded triangles is 1+2+3=6;

the number of shaded triangles in pattern 2 is also 6.

From observation the number of shaded triangles in pattern 50 would be the sum of (1+2+3+…+51);

the number of unshaded triangles in pattern 50 would be (1+2+3+…+50).

The difference is 51.
