If 2 n - 1 is the n th term of a GP Write out t... - SS2 Mathematics Sequence and Series Question
If \(2^{n - 1}\) is the \(n\)th term of a GP. Write out the first three terms of the sequence.
\[T_{n} = 2^{n - 1}\]
\[T_{1} = 2^{1 - 1} = 2^{0} = 1\]
\[T_{2} = 2^{2 - 1} = 2^{1} = 2\]
\[T_{3} = 2^{3 - 1} = 2^{2} = 4\]
The first three term of this GP are \(1,\ 2\ and\ 4\)
