Find an explicit formula for the geometric sequence -25, -50, -100,- 200,
Note: the first term should be d(1).
d(n)
-25*2^n-1

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
