Is the sequence (a) (1.2,2.4,4.8,9.6. arithmetic, geometric, or neither? if arithmetic, identify the common difference, d. if the sequence is geometric, identify the common ratio, r.

(C) geometric, r = 2

Step-by-step explanation:

Each term is multiplied by 2 to create the next term.  Multiplication makes this a geometric sequence. Since it is multiplied by 2, r = 2.

NOTE: If the terms were added, then it would be an arithmetic sequence.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
