The change from one number to the next in a geometric sequence is called the: a. common ratio b. arthimetic differnce c. geometric ratio d. common difference

Option 'A' is correct.

Step-by-step explanation:

Since we know that

The change from one number to the next in a geometric sequence is called the common ratio.

As geometric series contains those terms which have constant ratio between consecutive terms.

Common ratio of geometric series is defined as

Second term : first term

Hence, option 'A' is correct.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
