How would I find the expression of the nth term sequence given the terms of 2, 1, 4/5, 5/7, 6/9 and the expression of the nth term sequence given the terms of 1/2,-1/4,1/8, -1/16
Given: 1, 1/2, 3, 1/4, 5...Find the nth term of the sequenceI know the pattern is "n" for all odd terms and "1/n" for all even terms but is there a way to write this in one formula for the nth term of the sequence?
Find the first 4 terms of the sequence with nth term given by a n = (n-1)!/(2n+1)!
The sum of the first 100 terms of the sequence 1, -2, 3, 4, -5, 6, 7, -8, 9, 10 is 1750. The sum of the first 100 terms of the sequence 1, 2, -3, 4, 5, -6, 7, 8, -9, 10 is equal to (A) 1684 (B) 1717 (C) 1783 (D) 1816 (E) None of these

what is the next term in the geometric sequence 16,-4,1,-1/4
Find out a formula for the Nth term of each of the following sequences.(i)4 7 10 13 16(ii)1 3 5 7 9 (iii)20 17 14 11 8 (iv)1 4 9 16 25(v)2 8 18 32 50
Find the twelfth term of the geometric sequence: 1/16, 1/8, 1/4.... Common ratio: 1/2 I got the ratio by dividing 1/16 by 1/8 which gave me 1/2 and I divided 1/8 by 1/4 to get 1/2-----That is how I got a common ratio of 1/2. In order to obtain the 12th term I think I messed up somewhere: a12=(1/16)(1/2)^12-1 which gave me 3.05E I don't think that is right but don't know where I went wrong. Help!!! Thanks
Find the value of the following fractional expression:10/1 + 9/2 – 8/3 – 7/4 – 6/5 – 5/6 – 4/7 – 3/8 – 2/9 – 1/10Provide your answer as a simplified fraction.
Could someone please explain to me how to find an algebraic expression to calculate the nth term of the following sequence?: 2, 5, 11, 23, 47, 95, 191 I know that the equation to continue the series is 2x+1, but I've tried for 2 hours to figure out an equation for the nth term, and all I've gotten is frustrated! Thanks so much for any help!!
