Question

Observe the pattern below. -1, -2, 2, -1, -2, 2, -1, -2, 2, -1, -2, 2,.... Which of the terms in this pattern would be POSITIVE?

Answer 1

Answer:

To establish a rule for a number pattern involving ordered pairs of x and y, we can find the difference between every two successive values of y. If the difference pattern is the same, then the coefficient of x in the algebraic rule (or formula) is the same as the difference pattern.
