Math Problem Statement
Solution
The image shows a sequence of alternating squares and triangles with numbers inside them. The task is to determine the missing number inside the last triangle, with the following shapes and numbers:
- Square: 3
- Triangle: 21
- Square: 8
- Triangle: 2
- Square: 81
- Triangle: ?
The answer choices provided are:
- (A) 18
- (B) 34
- (C) 36
- (D) 44
Analyzing the pattern:
- The squares have numbers that follow a specific rule, and the triangles seem to relate to those numbers.
- Observing the relationship between the square and triangle pairs:
- Square (3) and Triangle (21)
- Square (8) and Triangle (2)
- Square (81) and missing Triangle (?)
First Pair (Square: 3, Triangle: 21)
Multiplying the square’s value (3) by 7 gives us 21, which matches the number in the triangle.
Second Pair (Square: 8, Triangle: 2)
Multiplying the square’s value (8) by 0.25 gives us 2, the number inside the triangle.
Third Pair (Square: 81, Triangle: ?)
Applying the same logic, multiplying the square’s value (81) by 0.5 gives us: However, this is not among the answer choices, so the pattern might involve rounding or different scaling.
Let's review and find a more precise pattern.
