Question

Which of the following is/are correct for an AP whose common difference is d.

• A. If d$>$0, then AP is decreasing.
• B. If d$<$0, then AP is increasing
• C. If d = 0, then all the terms of AP are the same.
• D. None of the above is correct.

Answer 1

The correct option is C

If d = 0, then all the terms of AP are the same.

For an AP whose common difference is d,

If d$>$0, then AP is increasing

If d$<$0, then AP is decreasing

If d = 0, then all the terms of AP are the same.
