Answer 1

Answer:

The sum of successor of 'n' and predecessor of 'n' is. A. n. B. n2. C. 2n. D. None of these. Answer. Successor of n=n+1.

Successor of n=n+1.

Predecessor of n=n−1.

∴ Sum of (n+1)+(n−1),

Answer 2

Concept: Successor: The successor of a given number is the one that comes right after it.

Predecessor: A number's predecessor is the one that immediately precedes it.

A full number's predecessor is one less than the provided number.

Given: The number 'n'

To find: Sum of successor of 'n' and predecessor of 'n'

Solution: Successor of n = n + 1

Predecessor of n = n - 1

Therefore, sum of successor of 'n' and predecessor of 'n' will be

(n + 1) + (n - 1)

n + 1 + n - 1

2n

Hence, sum of successor of 'n' and predecessor of 'n' will be 2n.
