WebTo find any term in a geometric sequence use this formula: xn = ar(n–1) x n = a r ( n – 1) a = a = the first term, r = r = the common ratio, n = n = number of items Geometric Sequences – Example 1: Given the first term and the common ratio of a geometric sequence find the first five terms of the sequence. a1 = 3,r = −2 a 1 = 3, r = − 2 Solution: WebThen the square root can be approximated with the partial sum of this geometric series with common ratio x = 1- (√u)/ε , after solving for √u from the result of evaluating the geometric series Nth partial sum for any particular value of the upper bound, N. The accuracy of the approximation obtained depends on the magnitude of N, the ...
