Sequence and series

If a,b,c be in geometric progression and log a, log b, log c be in arithmetic progression, then show that the common difference of the arithmetic progression must be 3/2.

@rushabhjain I think the question is wrong
If a,b,c are in GP, then loga,logb,logc are definitely in AP

@mohdsabirshaikh this is a right question

@rushabhjain Can you please post the printed text of the question
