# Math Help - Urgent HW help

1. ## Urgent HW help

Provide a relation on the integers that
a) is reflexive, is symmetric, but is not transitive

b) is not reflexive, not symmetric, and is transitive

Help?!

2. Try this relation for part a.
$nRm\, \Leftrightarrow \,\left| {n - m} \right| \le 1$

For part b, think about 'less than'.

3. Thank you so much! I've got it now
