The number that is one less than 7000, that is, 7000 - 1.
Every integer has a predecessor and a succesor. If you mean NON-NEGATIVE whole numbers, the answer would be zero.
use MATHS plz
The predecessor of 1 is 0. If you define "natural numbers" as starting at 1, then 1 has no predecessor. (Natural numbers can be defined either to include, or to exclude, zero.)
It is called a whole number. Every whole number, other than 1 can be divided evenly by 1. 1 itself can be divided evenly by -1. Thus, every whole number can be divided evenly by another whole number.
