What is the common ratio between successive terms in the sequence? 2, -4, 8, -16,

the answer is f(x) = n*(-2)

ratio is the wrong word to use, it is for contolled variation in probability. a sequence is controlled by what is known as a function - f(x) is the symbol for a function

Step-by-step explanation:

the following number of the previous one in the sequence is derived by the function f(x)=n*(-2)

2 x -2 = -4 (positive x negative = negative)

-4 × -2 = 8 (negative x negative = positive)

8 x -2 = -16 (positive x negative = negative)

so in the sequence, the trend of -,+ double will go on

i dont get it. where are the "descriptions"?

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4
