Definition of geometric sequence
WebThe top tab provides students with notes/ definition of a geometric sequence, an example, and space to write and label the explicit formula. The three tabs at the bottom provide examples. Each example will ask students to find the next term in the sequence, write the explicit formula, and then use the formula to find a given term in the sequence. WebMar 21, 2024 · geometric series, in mathematics, an infinite series of the form a + ar + ar2 + ar3+⋯, where r is known as the common ratio. A simple example is the geometric series for a = 1 and r = 1/2, or 1 + 1/2 + 1/4 + 1/8 +⋯, which converges to a sum of 2 (or 1 if the first term is excluded). The Achilles paradox is an example of the difficulty that ancient …

WebOct 24, 2024 · Solution. Finding the common ratio is a matter of dividing any term by its previous term: 45 15 = 3 = r. Therefore, the general term of the sequence is: a n = 15 ⋅ 3 n − 1. The general term gives us a formula to find a 10. Plug n = 10 into the general term a n. a 10 = 15 ⋅ 3 10 − 1 = 15 ⋅ 3 9 = 295245. Example 8.3.2.
