Unformatted text preview: \ ( 19 - 30 Determine to love tore of False_ Prove the statement directly from` the definitions if it is tome , and give a counter example if false. 20 ) The sum of any three consecutive images is divisible by 3. (Two integers are consecutive if , and only if , one is more than the other. ( ox ) + ( a + 1 ) + ( 9 + 2 ) = ( 3 0 + 3 ) =\ 3 ( a + 1 )| So the statement is true because 3 is the divisor we are looking for and att can be an integer . ..!` 24 ) for all integers arb , and C , if albo and all than a | ( 25 - 30 ) . By definition of divisibility` we know that b = as and C = as for some integers I and S. so 26 - 36 = 2car ) - 3 ( As ) - 2 ar - 3 95 `A = = = ( 25- 35) Since { and } on both integers and I and I are both interers , their products will be integers and the equation is true by the definition of divinable 281 for all integers Garb , and `` if albe then all of all FALSE. if a : 8 6 : 2, 6 : 4 \\ 5 . 6: 8 4 160 is true but all and alc are false...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
