variation

1,-3,2,5,-4,-6

Three

1 * -3 = 1st pair
-3 * 2 = 2nd pair
5 and -4 = 3rd pair

your explanation is too brief and confusing

I'll give it a shot.

The question is referring to consecutive terms of the sequence 1,-3,2,5,-4,-6

Therefore, you cant arrange this sequence in ascending or descending order.

variation = product of consecutive positive and negative TERMs.

1 * -3 = -3

-3 * 2 = -6

-4 * 5 = -20

Thus, 3 is the answer.

Hope this helps.

Hey thanks

why 1 and -3 are "consecutive positive and negative TERMs"? just because -3 goes right after 1 in this specific sequence?
thanks

Absolutely!
