Scalene, isosceles, and equilateral triangles
Scalene, isosceles, and equilateral triangles
What you'll learn
- Identify the common ratio of a geometric sequence given at least three consecutive terms, and express it as a simplified fraction or integer with 100% accuracy.
- Solve for a specified term (a_n) in a geometric sequence, given the first term (a_1), the common ratio (r), and the term number (n), with at least 80% accuracy in application problems.
- Apply the formula for the nth term of a geometric sequence (a_n = a_1 * r^(n-1)) to calculate missing terms, including scenarios involving fractional or negative common ratios, and verify the results using iterative multiplication with 75% accuracy.
- Explain, in writing, the relationship between the explicit formula (a_n = a_1 * r^(n-1)) and the recursive definition (a_n = r * a_(n-1)) of a geometric sequence, demonstrating an understanding of how each can be used to determine subsequent terms with clear and concise reasoning.
