1. The members of the sequences are defined by the formulas:
1) \(x=|n-3|\)
4) \(t=2^{|n-2|+1}\)
2) \(y=(-1)^{n}\)
5) \(v=(-1)^{n} \cdot n\)
3) \(z=(-1)^{n}-|n-5|\)
6) \(w=\left|2^{n}-n^{2}\right|\).

Does each of these sequences have a greatest member? A least member?

32
1) The smallest term is the third. It equals zero.

2) The smallest terms have odd indices, they equal -1. The largest terms have even indices, each equals 1.

3) The largest terms are the fourth and sixth, each equals zero. There is no smallest term.

4) The smallest term is the second, there is no largest term.

5) The sequence has neither a largest nor a smallest term.

6) The smallest terms are the second and fourth, they equal zero.
