To find the predecessor of a number we move from right to the left on the number line
And , −17 lies on left side of −16
Hence, −17 is the predecessor of −16
Option (B) is the correct answer

It's -17 because in number line the number -16 is after -17 thus the predecessor of -16 is -17.
-16-1=-17

Understanding Predecessors
The predecessor of a number is defined as the number that comes immediately before it in the number line. To find the predecessor of a given number, you simply subtract 1 from that number.
Finding the Predecessor of -16
Let's apply this concept:
- The number in question is -16.
- To find its predecessor, we perform the calculation:
-16 - 1 = -17.
Options Analysis
Now, let's evaluate the options provided:
- a) -15 (This is greater than -16, so it cannot be the predecessor.)
- b) -17 (This matches our calculation, as -17 is indeed the predecessor of -16.)
- c) -17 (This is a repeat of option b, which is still correct.)
- d) 15 (This is far greater than -16 and cannot be a predecessor.)
- e) 17 (This is also greater than -16 and not a predecessor.)
Conclusion
Based on the calculation and analysis of the options, the correct answer is option 'B', which is -17.
This confirms that the predecessor of -16 is -17, making option 'B' the most accurate answer.
