Question

what value we should choose for 4 cosecutive numbers in an AP and why does it so

Answer 1

We should choose (a - 3d), (a - d), (a + d) and (a +3d)

So that we can get the value of first term......Because the common differences will be cancelled.

Answer 2

We should choose (a - 3d), (a - d), (a + d) and (a +3d)

So that we can get the value of first term......Because the common differences will be cancelled.
