*EXTRA POINTS ASAP* Answer the boxes :)
First Dropbox option is “A geometric or an arithmetic” second box options is “common difference or common ratio” third box you type in.

This is geometric sequence and the common ratio is equal to ⅓.

Step-by-step explanation:

A geometric sequence has a common ratio which is gotten when we divide a term by the subsequent term in a sequence. The common difference would be the same for every two consecutive terms we divide by each other.

Thus:

8/64 = ⅛

1/8 = ⅛

Common ratio = ⅛

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
