1 million = 1,000,000
The successor of a number is one morethan that number and the predecessor of a number is one less than that number.
The successor of 1,000,000 = 1000000+ 1 = 1000001
The predecessor of 1,000,000 = 1000000- 1 = 999999
The difference between the successor and the predecessor of1,000,000 = 1000001 - 999999= 2.
In fact the difference between the successor and predecessor of any number will always be 2 !! Try it yourself
