Geometric Sequences

Translate between explicit and recursive forms of geometric sequences (subscript notation)

For each geometric sequence, translate from the explicit form into the recursive form (or visa versa) using subscript notation.

First term: \(15\)

\(g_n = 15\cdot 2^{n-1}\)

Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.^*
