The sum of any two consecutive integers is a composite number.

Question

A.
16 + 17 = 33

B.
10 + 11 = 21

C.
6 + 7 = 13

D.
7 + 8 = 15

Answer 1

clearly false
All you need is one exception to the rule and the rule becomes bogus

since 6+7 = 13 and 13 is NOT a composite number
the statement is false.

Answer 2

Thanks
