Given parameters:

Terms of the sequence  = 7/8 , 3/4 , 9/14

From terms, we know that our first term is  [tex]\frac{7}{8}[/tex]

We need find either of the common difference or the common ratio of this sequence.

For this, the common ratio is applicable.

  Common ratio  = [tex]\frac{3}{4} / \frac{7}{8}[/tex]

 This is the factor by which when we multiply the subsequent terms with results into them;

     Solving the above gives [tex]\frac{6}{7}[/tex]

The common ratio is 6/7.

To find the nth of this sequence we apply the formula below;

            A[tex]_{n}[/tex]  = Arⁿ⁻¹

Aₙ is the term we are looking for

A is the first term of the sequence

r is the common ratio

n is the position of the term

  So for any nth term in this sequence;

         Aₙ   = [tex]\frac{7}{8}[/tex] x [tex]\frac{6}{7}[/tex] ⁿ⁻¹

We can use the above solution to find any term in the sequence.
