What is the (n)th term of the sequence \(12,6,3,\frac{3}{2},\ldots\)?
Advertisement
Answer and explanation
Correct answer: \(12\left(\frac{1}{2}\right)^{n-1}\)
Each term is multiplied by \(\frac{1}{2}\), so \(a_n=12\left(\frac{1}{2}\right)^{n-1}\). Keep the first term separate in a geometric sequence.
