the common ration of a geometric sequence is 5. what are the first four terms of the sequence if its first term is 4.5?

Answer 1

The common ratio of a geometric sequence is the quotient of any term in the sequence divided by the term that comes before it.

If the common ratio is 5, and the first term is 4.5, the second term would be 4.5 * 5 = 22.5, the third term would be 22.5 * 5 = 112.5, and the fourth term would be 112.5 * 5 = 562.5.

Therefore, the first four terms of the geometric sequence with a common ratio of 5 and a first term of 4.5 are 4.5, 22.5, 112.5, and 562.5.
