Answer 1

Thus, Successor of 87 is 88, predecessor of 72 is 71, predecessor of the predecessor of 45 is 43, Successor of the successor of 32 is 34.

Step-by-step explanation:

• The successor of a number is the number which comes just after it.

• On the other hand, the predecessor of a number, which comes immediately before it.

For eg,

   (1) 101 and 102

• 101 is the predecessor of 102.

• 102 is the successor of 101.

   (2) 156 and 157

• 156 is the predecessor of 157.

• 157 is the successor of 156

Similarly, we are given as;

• (a) Successor of 87 is 88.

• (b) predecessor of 72 is 71.

• (c) predecessor of the predecessor of 45 => predecessor of the (predecessor of 45)

    =  predecessor of (44)

    = 43

• (d) Successor of the successor of 32 => Successor of the ( successor of 32)

    =  Successor of (33)

    = 34

Thus, Successor of 87 is 88, predecessor of 72 is 71, predecessor of the predecessor of 45 is 43, Successor of the successor of 32 is 34.
