Find the nth term of the sequence: (-2 / 1), (8 / 2), (-26 / 6), (80 / 24), (-242 / 120) . . . How do you find the nth term of the sequence 2,5,10,17,26,37,...? How do you find the nth term of the sequence 2, 4,...
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by ( 1/4) gives the next term. In other words, ( a_n=a_1⋅ r^(n-1)).Geometric Sequence: ( r=1/4)This is the form of a geo...
you may be asked to solve problems with cubic sequences. As the name implies, cubic sequences rely on powers no higher than 3 to find the next term in the sequence. Depending on the complexity of the sequence, quadratic, linear and constant terms may also be included. The general form f...
To find a given term of the sequence, we substitute the value of {eq}n {/eq} in the {eq}n^{th} {/eq} term of the sequence. Answer and Explanation: Given data: {eq}a_n = \dfrac{2^n}{2^n +1} {/eq} {eq}a_6 {/eq} means the sixth term of the ...

Notice that the amount being subtracted is increasing by 12 each time. So the next subtraction will be 54, and the one after that will be 66. So the next term is -77 - 54 = -131 And the term after that is -131 - 66 = -197 So the sequence would be: 13,-5,-35,-77,-131,...
