Answer 1

Could you snap the options as well or is it like that only? I can barely see it too :o

Answer 2

which of the following is true for all consecutive integer m and n such that m < n ?

Answer 3

A m is odd
B n is odd
C n-m is even
D n^2-m^2 is odd
E m^2+n^2 is even

Answer 4

Oh, less than I read greater than. I'd say D. Let me explain,

Answer 5

Assign the variables m and n a number, because it asks for consecutive integers, or two numbers that are in order. Example: 1,2 or even 40,41

'm' must be less than 'n' so if you assign m=1 and n=2

D: 2^2 - 1^3 = 4-1 = 3
Does that help?

Answer 6

@LilySwan did you understand it? 3 is odd.

Answer 7

ok why did you place 1 ^3 and not 1^2

Answer 8

Because your option said; n^2-m^2

Answer 9

I used 2 for n and 1 for m.

Answer 10

Understand? I just plugged in values.

Answer 11

that i understood im talking about the power for n you chose 2^2 but for m 1^3

Answer 12

Oh you mean why its being cubed, 2^2 - 1^2 = 4 - 1 = 3. Sorry typo. 1^3 is still 1 :P

Answer 13

@LilySwan :D Understand?

Answer 14
