Is each conjecture correct or incorrect? If its incorrect, give a counterexample
1. The difference of two numbers is less than or equal to each number
2.The sum of two negative numbers is always less than each number
3.The sum of 5 and any positive interger is divisible by 5
4. A number is divisible by 10 if its last digit is 0
5. The sum of a number and its absolute value is always 0
6. The next number in the pattern 2,4,8,.....is 10
7. Every even number is divisible by 4,
8. The next number in the pattern 5,3,1...is -1
Thnxx :)

1F 5-2=3

3F (5+1)=6. 6 is not div by 5
4 T
5 F 7+ |7|<>0
6 depends on the rule. If adding, add 2, add 4, add 6, the next number is 14
If multiplying by 2, the next number is 16. If the rule is add2, add4, add 2, add 4, then the next is 10:) Other number patterns could be found.
7 F. 2 is not div by 4
8 T if the rule is subtract 2
Good luck!
