Question

determine if the statement is true or false if it is false explain why must be changing the statements and make it true if it's true explain why you believe to be true the common difference for a geometric sequence given 5:1 -1 negative 3 negative 5 negative 7 is 2

Answer 1

The common difference can be determined by subtracting the first term with the second term, second term with the third term, and so forth.

In this case we have:

`1-(-1)=1+1=2`
`-1-(-3)=-1+3=2`
`-3-(-5)=-3+5=2`

In this way we can determine that the common difference of the sequence is 2, so the statement is true.
