Question

11 How do you know if a sequence is an arithmetic sequence? A The sequence has a common difference (adding or subtracting to get to the next term) The sequence has a common ratio (multiplying or dividing to get to the next term)

Answer 1

Arithmetic Sequences are sequences that are gotten by adding (or subtracting) the same value to each term preceding it.

Geometric sequences are sequences that we get when we multiply (or divide) the same value to each term preceding it.

Arith Metic Sequences have common differences whereas Geometric Sequences have what's called the common ratio.

As for your question, the answer is A
