ii)
Justify whether it is true to say that the following are the nth terms of an AP.
iii)
Justify whether it is true to say that the following are the nth terms of an AP.
i)
Answer. [Yes]
Solution.
Hence, 2n – 3 is the nth term of an AP because the common difference is the same.
ii)
Answer. [No]
Solution.
Here the common difference is not the same
Therefore series is not the nth term of an AP.
iii)
Answer. [No]
Solution.
Here the common difference is not the same
