Look at the following sequence. 21, 42, 126, 504, if it is geometric sequence, choose the common ratio. if it is not geometric sequence, choose “ not geometric “

not geometric

Step-by-step explanation:

If the sequence is geometric then the common ratio r between consecutive terms should be equal

= 2

= 3

= 4

There is no common ratio between consecutive terms

Hence the sequence is not geometric

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
