- American Dream (allthetropes.org)
Seriously, what the American Dream entails is constantly up for debate, but it’s usually agreed that it involves all citizens being allowed to achieve what they want, or at least the opportunity to try. Often it is pointed out that different minorities have commonly been handicapped in chasing the American Dream compared to other Americans.
- Sequence (Wikipedia)
In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, the same elements can appear multiple times at different positions in a sequence, and unlike a set, the order does matter. Formally, a sequence can be defined as a function from natural numbers (the positions of elements in the sequence) to the elements at each position. The notion of a sequence can be generalized to an indexed family, defined as a function from an arbitrary index set.
