Answer:

THE CORRECT ANSWER IS 25 NOT 15

ANSWER :- (c) 25

Step-by-step explanation:

The answer is 15 not 25.

The answer is 15 not 25.Given, 120 , 80 , 40 , 45 , ? , 5

This series is the combination of two different series . 120, 80 , 40 and 45, ? , 5

Here in 120, 80, 40 are in AP where common difference is -40

Similarly we have to make 45 , ? , 5 in AP

Now if we take 25 in place of ?

We get, 45 , 25 , 5

Hence, correct answer should be 25.
