Recognizing this multiplicative relationship is key to solving problems involving these sequences. Negative ratios create an alternating pattern of positive and negative terms, adding a dynamic oscillation to the progression.
Geometric Sequence Explicit Formula Explained: Find the nth Term
If the result is the same number every time, you are looking at a geometric sequence. Conversely, if the ratio is a fraction between -1 and 1, the sequence shows exponential decay, with the numbers shrinking toward zero.
A geometric sequence is a list of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. For example, in the sequence 3, 6, 12, 24, the common ratio is 2, because each number is double the one before it.
Geometric Sequence Explicit Formula Explained
If the first term is denoted as a₁ and the common ratio as r, the nth term is calculated as aₙ = a₁ * r⁽ⁿ⁻¹⁾. Compound interest in finance, the decay of radioactive materials in science, and the rebound heights of a dropped ball all follow this pattern.
