Finding Geometric Sequences Using Non-Consecutive Terms
When given two non-consecutive terms of a geometric sequence, use the general formula to create a system of equations. If and , then: Key formulas include expressions such as a_n = a_1 \cdot r^{n-1}. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 8: Sequences and Series.
Key Concepts
When given two non consecutive terms of a geometric sequence, use the general formula $a n = a 1 \cdot r^{n 1}$ to create a system of equations. If $a m = A$ and $a n = B$, then: $$a m = a 1 \cdot r^{m 1} = A$$ $$a n = a 1 \cdot r^{n 1} = B$$.
