Calculation:
Subtract the first term from the second term of the sequence to obtain the difference of sequence.
Subtract the second term from the third term of the sequence to obtain the difference of sequence.
Difference is not same; therefore, it is not an A.P.
Divide the second term with the first term of the sequence to obtain the ratio of sequence.
Divide the third term with the second term of the sequence to obtain the ratio of sequence.
