Question

3, -5, 11, -21, 43... How does each term relate to the next term? A) Subtract 8. B) Multiply by -2 and add 1. C) Multiply by -3 and add 4. D) Multiply by 2 and subtract 1.

Answer 1

The answer is B.

Each term (3,-5,11, -21, 43) are all the result of the previous one multiplied by -2 and add 1.

3 * -2 = -6 +1 =5
-5*-2= 10+1=11
