The pattern "square, triangle, circle, oval" consists of 4 shapes that repeat in that order.
To determine the 50th shape, we can use the formula for finding the position within a repeating sequence:
- Divide the position by the number of unique shapes: \( 50 \div 4 = 12\) with a remainder of \( 2 \).
The remainder tells us the position in the sequence:
- Remainder 1 corresponds to "square"
- Remainder 2 corresponds to "triangle"
- Remainder 3 corresponds to "circle"
- Remainder 0 corresponds to "oval" (when complete)
Since the remainder is 2, the 50th shape is a triangle.
