the hypotenuse may be found by using the Pythagoras theorem

As

, the sequence

converges to zero.
If you're talking about the infinite series

well we've shown by comparison that this series must also converge because we know any geometric series

will converge as long as

.
The two numbers are both -15
-15 x -15= 225
-15+ -15= -30
