Answer:
1. (+1)(+2)
2. (−2)(+3)
3. (−2)(+1)
Step-by-step explanation:
That's correct but whats your question?
First number --- (2a-1)
middle number ---- (2a)
third number -----(2a+1)
2a-1+2a+2a+1=250
6a=250
a=250/6= 125/3
2a=2*(125/3)= 250/3 ---- is not a whole number that is contradicts to what is given, so sum cannot be 250
so
Three or more points that lie on the same line are collinear points. for example let’s say points D , B and E like on line N. does this help?
