1 * -3 = negative
-3 * 2 = negative
5 * -4 = negative

So, the number of variations in sign = 3

[spoiler]The correct answer is (C).[/spoiler]

Isn't the answer two? It says consecutive terms. I am a bit confused by the definition of the number of variations.

1* -3 = negative
-3* 2 = negative
2*5 = positive
5*-4 = negative
-4*-6 = positive
