Question

Is the sequence geometric ? -48,96,-192,384...

Answer 1

Answer:

yes

Step-by-step explanation:

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

$\frac{96}{-48}$ = - 2

$\frac{-192}{96}$ = - 2

$\frac{384}{-192}$ = - 2

The common ratio between terms = - 2

Hence the sequence is geometric
