Question

write the predecessor and successor of 49

Answer 1

Predecessor = Number - 1
Successor = Number + 1

$49 - 1 = 48 \\ 49 + 1 = 50$

Answer 2

Answer:

The predecessor of 49 is 48.

The successor of 49 is 50.

Step-by-step explanation:

• If a and b are two integers such that a is the successor of b, then we can write : a = b+1
• If a=b+1 , then a - b = 1
• Predecessor and Successor: Predecessor and Successor are the two terms  that are most commonly used for the series and sequence of whole numbers.
• The predecessor is the before numbers that appear just before the given number and the successor is  after numbers which appears just after the given number.
• For example, in the series 10, 11,12, 13, 14 ... 11 is the predecessor of 12 and 13 is the successor of 12.
• Suppose a value is x which belongs to any whole number, then the predecessor of x will be (x-1) . Hence, we can say that, to find the predecessor of any value we have to subtract 1 from the give

        value .

• Suppose a value is x which belongs to any whole number, then the successor of x will be (x+1) . Hence, we can say that, to find the successor of any value, we have to add 1 to the give value .
