The following sequences' first ten terms should be given. Assume that the sequences are in base 2 and have an index of 1.
Indicate whether the sequence is increasing, decreasing, non-increasing, or non-decreasing.
1) The nth term is the largest integer k such that k!n.
2) The nth term is 1/n.
3) The nth term is 3.
4) The nth term is n2.
5) The nth term is [logn].

1) The nth term is the largest integer k such that k!n.
First term n=11!1
n=22!2
n=32!3, 36
n=42!4
n=52!5
n=63!6
n=73!7, 424
n=83!<8
n=93!<9
n=103!<10
So, first terms are 1,2,2,2,2,3,3,3,3,3

3) The nth term is 3.
<an<3>
Sequence is always the same.
First ten are <3,3,3,3,3,3,3,3,3,3> - non-decreasing and non-increasing
5) The nth term is [logn]
It's ceiling function
log1=0
log22=1
2<log25<3
2<log7<3
3<log9<4
1<log23<2
log24=2
2<log6<3
log8=3
3<log10<4
Thus, <an[logn]
First ten terms are <0,1,2,2,3,3,3,3,4,4>
Non-decreasing
