Replied to the first one in your earlier post ..




From 1 O could be between or maybe not
a,b = 3 ,1 distance greater but not between
a,b = 3 ,-1 distance greater but between

Yes and no

Hence insufficient

From 2

take a = 3 b = 1 condition does not hold true

for the condition to hols 0 has to between a and b
take a case where 0 is between a and b like 3 ,-1

It wil always be true for any others numbers as well

Hope this helps
