The successor and predecessor of a complete quantity are mentioned under:

The quantity that comes simply earlier than a quantity is known as the predecessor. So, the predecessor of a given quantity is 1 lower than the given quantity. Successor of a given quantity is 1 greater than the given quantity. 

For instance, 9,99,99,999 is predecessor of 10,00,00,000 or we will additionally say 10,00,00,000 is the successor of 9,99,99,999.

Definition of Successor:

The quantity which comes instantly after a selected quantity is known as its successor.

Tips on how to discover the successor of a quantity?

The successor of a complete quantity is the quantity obtained by including 1 to it.

Clearly, the successor of 0 is 1; successor of 1 is 2; successor of two is 3 and so forth.

We observe that each complete quantity has its successor.

Quantity + 1 = Successor

Definition of Predecessor:

The quantity which comes simply earlier than a selected quantity is known as its predecessor.

The predecessor of a complete quantity is one lower than the given quantity.

Tips on how to discover the predecessor of a quantity?

Clearly, the predecessor of 1 is 0; predecessor of two is 1; predecessor of three is 2 and so forth.

The entire quantity 0 doesn’t have any predecessor.

We observe that each complete quantity, apart from zero, has its predecessor.

Additionally, if a is the successor of b, then b is the predecessor of a.

Quantity + 1 = Predecessor

Solved Examples on Successor and Predecessor of a Quantity:

Discover the successor and predecessor of every of the next complete numbers:

(i) 1000

(ii) 11999

(iii) 400099

(iv) 1000001

(v) 99999

Resolution:

(i) 1000

The successor of 1000 is (1000 + 1) = 1001.

The predecessor of 1000 is (1000 – 1) = 999.

(ii) 11999

The successor of 11999 is (11999 + 1) = 12000.

The predecessor of 11999 is (11999 – 1) = 11998.

(iii) 400099

The successor of 400099 is (400099 + 1) = 400100.

The predecessor of 400099 is (400099 – 1) = 400098.

(iv) 1000001

The successor of 1000001 is (1000001 + 1) = 1000002.

The predecessor of 1000001 is (1000001 – 1) = 1000000.

(v) 99999

The successor of 99999 is (99999 + 1) = 100000.

The predecessor of 99999 is (99999 – 1) = 99998.

What’s Successor and Predecessor of a quantity?

The Successor and Predecessor of a quantity are defined utilizing examples.

           PREDECESSOR                NUMBER                SUCCESSOR

          (7148 – 1) 7147                 7148                  (7148 + 1) 7149

          (8950 – 1) 8949                 8950                  (8950 + 1) 8951

          (7620 – 1) 7619                 7620                  (7620 + 1) 7621

        (12499 – 1) 12498              12499                 (12499 + 1) 12500

To search out the predecessor of a quantity, subtract 1 from the given quantity.

To search out the successor of a quantity add 1 to the given quantity.

(ii) The successor of 10,00,999 is (10,00,999 + 1) = 10,01,000

(iii) The successor of 49,99,999 is (49,99,999 + 1) = 50,00,000

(iv) The successor of 48,09,826 is (48,09,826 + 1) = 48,09,827

(v) The successor of 8,00,78,593 is (8,00,78,593 + 1) = 8,00,78,594

2. Write the predecessor of the given numbers.

(ii) 89,78,515

(iii) 78,45,000

(iv) 99,30,799

(v) 85,83,221

Resolution:

(i) The predecessor of 47,89,300 is (47,89,300 – 1) = 47,89,299

(ii) The predecessor of 89,78,515 is (89,78,515 – 1) = 89,78,514

(iii) The predecessor of 78,45,000 is (78,45,000 – 1) = 7844999

(iv) The predecessor of 99,30,799 is (99,30,799 – 1) = 99,30,798

(v) The predecessor of 85,83,221 is (85,83,221 – 1) = 85,83,220
