Question

Help please. Is the sequence geometric?

Answer 1

• Yes, the sequence is geometric.
• This is because of we multiply 4 with -5, we get -20.
• $4 \times - 5 = - 20$
• Similarly, if we multiply 100 with -5, we get -500.
• $100 \times - 5 = - 500$
• So, the common ratio is -5.

Answer:

yes, -5
