principal for step analysis -
understand color pattern first then odd and even direction analysis
1.) all 4 numbers must move in one direction
2.)we must have 2 odds , 2 evens
-3.) we cannot cross zones after 1 number , eg . after 1 red no. then blue number .
4.) color patterns we need for this step analysis are-
- all 4 numbers in blue
- all 4 numbers in red
-2 first numbers in red,then blue
- 2 first numbers in blue, then red
keep practicising larger red negative number should be on the left. learn 2 analyze 2 red numbers at a time.
