Which best describes the relationship between the successive terms in the sequence shown? 2.4, –4.8, 9.6, –19.2

The common difference is –7.2.
The common difference is –2.4.
The common ratio is –2.0.
The common ratio is –0.5.

THE ANSWER IS THE COMMON DIFFERENCE IS -7.2 (first answer)

PLEASE MARK BRAINLIEST :)

Take any term and subtract the one before it. -4.8 - 2.4 = -7.2 but -19.2 - 9.6 = -28.8 so the difference is NOT common
Dividing pairs of terms gives -4.8 / 2.4 = -2. 9.6 / -4.8 = -2. -19.2 / 9.6 = -2 so there is a common ratio of -2

Main idea on left, details on right
