4)Sequences & Series

Formulas to remember:
Arithmetic Sequence (an)	${a_n} = {a_1} + (n - 1)d$
Arithmetic Series (Sn)	${S_n} = \frac{n}{2}\left( {{a_1} + {a_n}} \right)$
Geometric Sequence (An)	${a_n} = {a_1}\left( {{r^{n - 1}}} \right)$
Geometric Series (Sn)	${S_n} = \frac{{{a_1}\left( {1 - {r^n}} \right)}}{{1 - r}}$
