Consider the number 132 what is the number that comes just before 132? Yes, it is 131 Now what is the number that comes just after 132? It is very easy it is 133 here 131 is the predecessor of 132 and 133 is the successor of 132. So the predecessor of a number is the number that comes just before the number. That is 1 less than the number The successor of a number is the number that comes just after the number. That is 1 more than the number. Let us look at some examples consider a 4 digit number 2376. It's predecessor is 2376-1 that is = 2375. The successor of 2376 is 2376+1 that is 2377. Hello friends! I am Nisha. Look at this number line , I am going to use it to understand what number comes before and what number comes after a particular number consider the number 15 the number just on the left of it is 14 so the number 14 comes before the number 15 and the number just on the right of 15 is 16 so the number 16 comes after the number 15 so I can say that the number before any number can be obtained by subtracting one from it and the number after any number can be obtained by adding one to it. Here 14 is obtained by subtracting one from 15 and 16 is obtained by adding 1 to 15. Hello friends! I am Priya. I am going to tell you about skip counting. Skip counting is the counting of numbers by jumping one or more numbers. Let us learn skip counting in 4's starting from the number 0. Let me take this number line in skip counting in 4's starting from 0 I have to jump 4 times like this. Now I am at 4 next the same procedure will be followed, like this so we can lift the marked numbers as 0, 4, 8, 12 and so on. See in skip counting, in 4s the next number is obtained by adding 4 to the previous number.
