Bounded sequences
Let \( M >0 \) be a rational.
A finite sequence (of rationals, but equally applies to reals) \( a_1, a_2, a_3, ..., a_n \) is bounded by M iff [...] for all \( 1 \ge i \ge n \).
An infinite sequence \( (a_n)_{n=1}^{\infty} \) is bounded by M iff [...] for all \( i \ge 1 \).
A sequence is said to be bounded iff it is bounded by some \( M \ge 0 \).
