How do you find the nth term in a geometric and arithmetic sequance?
an arithmetic sequence follows the formula: a(subscript:n) = a(subscript:1) + (n – 1)d. in the above, a with subscript 1 is the first term in the sequence, d is the common difference between each term, and of course a with subscript n is the answer a geometric sequence follos this formula: a(subscript:n) = a(subscript:1)*r^(n – 1). in the above, r is the common ratio between the terms, essentially, the number that is bein multiplied each time to get the following term it was hard to write the formulas with the subscripts but if u need more info go here: http://www.purplemath.com/modules/series… hope i helped!
