Determine if the sequence 1, 2, 3, 5, 8, 13... is arithmetic, geometric, or niether. A. Arithmetic B. Geometric C. Niether
Weegy: Neither, because the numbers in an arithmetic sequence have a constant difference, (for example: 2, 4, 6, 8, 10...) and the numbers in a geometric sequence are constantly multiplied by a fixed number, (for example 1, 2, 4, 8, 16...) User: What is the common ratio of this geometric sequence? 1 80 2 40 3 20 4 10 5 5 A. -40 B. 0.5 C. 2 D. 40 Weegy: 40 User: Write the formula for the geometric sequence. 7, 21, 63, 189… A. an=7 3n-1 B. an=189 3n-1 C. an=7 3n D. an=189 3n Weegy: The geometric formula are as follows: Just multiply by 3: 7, 21, 63, 189, 567, 1701, [ 5103... The general formula for the geometric sequence is: a(n) = 7*3^(n-1) a(1) = 7*3^0 = 7 * 1 = 7 a(2) = 7*3^1 = 7 * 3 = 21 a(3) = 7*3^2 = 7 * 9 = 63 a(4) = 7*3^3 = 7 * 27 = 189 ] User: What is the common ratio of this geometric sequence? 1 50 2 30 3 18 4 10.8 5 6.48 A. -20 B. 0.6 C. 1.67 D. 20 Weegy: The common ratio of this geometric sequence: 1 50 2 30 3 18 4 10.8 5 6.48 is: 0.6.
