Jessica is making a reapeating pattern following the rule triangle,square,circle what will be the 50th shape in the pattern?
+486 We have the sequence: triangle, square, circle, triangle, square, circle, triangle, square, circle...
The $50^{th}$ shape is the same as $50$(mod $3$)$=2$, because the shape repeats every $3$ items. So the $50^{th}$ shape equals the $2^{nd}$ shape equals a $\boxed{square}$
