How does the order of terms affect the identity of a sequence?

• Order does not matter in sequences.

• Order is only relevant when using explicit formulas.

• Changing the order creates a different sequence.

• Order only matters in finite sequences.

What is the difference between infinite and finite sequences?

• Infinite sequences have a definite end, finite do not.
