Question

Question Use set-builder notation to describe the set of all odd integers. Select the correct answer below: O n O neZO * € Z O {2n +1 ne Z}

Answer 1

First let's define how to write the odd intergers:

When you have an odd it menas you have the result of a number multiply by 2 (or a even number) +1, so, if you need to express the odds you have:

2n+1

Now the ingergers are represented by the Z

Then so, the set of all odd integers is:

`2n+1\in Z`

where

∈ means belongs

Z means intergers

n is the n- umpteenth term.
