​

Answer 1

Option a is the answer bro

Answer 2

Answer:

successor and predecessor of-123

Successor of 123 is 124

Predecessor of 123 is 122

So, the correct option is : (A) Successor-124 Predecessor-122

Step-by-step explanation:

• 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 1, 2, 3,5 ... 1 is the predecessor of 2 and 3 is the successor of 2.
• 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 given

       value . So, Predecessor of 123 = 123 - 1 = 122

• Suppose, n is a number that belongs to any whole number, then the successor of n is ‘n+1’. Hence , we can say that, to find the successor of any value we have to add 1 to the given value .

        So, Successor of 123 = 123 + 1 = 124
