Question

Read the following conjecture.

Any number that is divisible by 2 is also divisible by 6.

Find a counterexample to show that the conjecture is false.

A 18
B 12
C 14
D 24

Thanks for any help guys. :)

Answer 1

Multiples of 2 are 2n and multiples of 6 are 6m the only time they are equal is when 6m=2n, n/m=3 or if you prefer n=3m...

This means that that is only true when the number is a multiple of 6.

In the list given, only 14 (c) is not a multiple of six so it disproves the original statement.

Answer 2

the correct answer is C 14 !!!! Your welcome
