Here is the copy of the practice exercises on Sequences, Series and Binomial Expansion. The file contains five (10) items. It contains:
- Arithmetic Sequence and Series
- Geometric Sequence and Series
- Binomial Expansion
For your reference, you may watch the playlist on sequences and series. The video will help you recall the notations and terms used for arithmetic progressions.
