Answer:

324, -972, 2916

Step-by-step explanation:

Divide a number by the previous number to find r.

r = -12/4 = -3

Multiply a number by r to find the next number.

-108 * (-3) = 324

324 * (-3) = -972

-972 * (-3) = 2916

Answer: 324, -972, 2916

Which number has both 2 and 5 as prime factors?
musickatia [10]

Answer:

Any multiple of 10

Step-by-step explanation:

A factor is defined as "a number or quantity that when multiplied with another produces a given number or expression." For example, the factors of 20 are 1, 2, 4, 5, 10, and 20.

When we multiply 2 and 5 together, we get 10. Multiplying this by anything else besides 0 will still yield something that has 2 and 5 as factors, for example 2 times 5 times 3 is 30. As this is just the same thing as multiplying 10 by 3, the answer is any multiple of 10.
