WebOct 23, 2016 · The fifth is 10. Find the first term. In this task we have 2 terms given: a2 = 4 and a5 = 10. We can use the n −th term formula to build a system of equations: {a1 + d = 4 a1 + 4d = 10. If we subtract the first equation from the second we can calculate d: 3d = 6; d = 2. Now if we substitute the calculated value we see that: a1 + 2 = 4, so a1 = 2. Weba 8 = 1 × 2 7 = 128. Comparing the value found using the equation to the geometric sequence above confirms that they match. The equation for calculating the sum of a geometric sequence: a × (1 - r n) 1 - r. Using the same geometric sequence above, find the sum of the geometric sequence through the 3 rd term. EX: 1 + 2 + 4 = 7. 1 × (1-2 3) 1 - 2.

WebEach successive term is multiplied by 3, so for any term n (where n>=1), its denominator would be 3^(n-1). Then notice that every numerator is 4 less than its denominator, so the formula for the numerator would be 3^(n-1) - 4. Putting these together, the terms of the sequence would be represented by the formula ( 3^(n-1) - 4 ) / 3^(n-1) where n>=1. WebOct 3, 2010 · See answer (1) Best Answer. Copy.
