What is the next term in the sequence? 2, –4, 8, –16, . . –24 –32 32 24

The answer is 32 Why?

Because since it's getting added by times 2 for every number the number after 16 would be 32 when doing 16 x 2 and since the last number being -16 was negative the number after it would be positive, also if you want it more straight forward the 32 cannot be negative because when you times a negative with a positive you get a positive. Hope this helps!

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
