Which sequence isn’t a geometric progression? 2, 6, 18, 54 1, 5, 25, 125 3, 6, 9, 12 or 4, 8, 16, 32?

25, 125 3, 6, 9, 12 or 4, 8, 16 is the correct answer.

Step-by-step explanation:

Geometric progression is also known as geometric sequence and it is a sequence of numbers where each term after the initial one is found by multiplying it by a commom ratio, which is a fixed, non-zero number.

The first sequence has 3 as the common ratio. The second one has 5 and the last one, 2. Option 3 doesn not have one, so it is the correct answer.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
