1.3+(2sn)−1 < 3+2(sn+1)−1

3+2sn-1< 3+2sn+1

increasing for all values n

2... i don't believe it is bounded from above,

A squence (Sn) is bounded above if there is a number M such that

Sn<= M for all n>=1 as this is continues to increase there's no M.

A squence (Sn) is bounded below if there is a number M such that

M<= Sn for all n>=1 this however is true. it is bounded below. M<2

3. limnsnof 3+2sn-1

3+2-1=
