In Geometric Sequences and Series, what does finite geometric sum mean?Geometric Sequences and Series
The total of a fixed number of geometric terms.
Why treat r=1 separately?Geometric Sequences and Series
The usual formula would divide by zero.
In Geometric Sequences and Series, what does convergent infinite sum mean?Geometric Sequences and Series
A finite limit of infinitely many geometric terms.
What condition allows convergence?Geometric Sequences and Series

In Sigma Notation, what does index and bounds mean?Sigma Notation
A compact instruction to add indexed values.
How many integer indices run from 1 through n?Sigma Notation
Exactly n indices.
In Sigma Notation, what does expanding a sum mean?Sigma Notation
Turning summation notation into an explicit addition.
Why expand a few terms?Sigma Notation
It reveals the index-to-term rule and bound count.

For arrangements or assigned roles, use a permutation count.
In Pascal's Triangle and Binomial Coefficients, what does pascal recurrence mean?Pascal's Triangle and Binomial Coefficients
A recurrence among adjacent combination counts.
What are the outside entries of every row?Pascal's Triangle and Binomial Coefficients
They are one.
In Pascal's Triangle and Binomial Coefficients, what does binomial coefficients mean?Pascal's Triangle and Binomial Coefficients
The numeric factors attached to binomial terms.
Why do term exponents add to n?Pascal's Triangle and Binomial Coefficients
Each factor contributes exactly one u or v.
In Binomial Theorem and Applications, what does general term mean?Binomial Theorem and Applications
A specified term of a binomial expansion.
Why does C(n,k) appear?Binomial Theorem and Applications
It counts ways to choose the k factors contributing v.
In Binomial Theorem and Applications, what does selected coefficient mean?Binomial Theorem and Applications
Extracting a particular binomial coefficient.
What changes if v contains a number?Binomial Theorem and Applications

In Binomial Theorem and Applications, what does applied patterns mean?Binomial Theorem and Applications
A connection between algebraic powers and selections.
Do probabilities equal bare binomial coefficients?Binomial Theorem and Applications
No, event probabilities also need outcome probabilities and assumptions.
