What is the 8th term of the geometric sequence a2 = 20 and r = 5

8th term of geometric sequence is 312500

Step-by-step explanation:

 Given :   and common ratio (r) = 5

We have to find the 8th term of the geometric sequence whose and common ratio (r) = 5  

Geometric sequence is a sequence of numbers in which next term is found by multiplying by a constant called the common ratio (r).

       ......(1)

where    is nth term and a is first term.

For given sequence

a can be find using   and r =  5

Substitute in (1) , we get,

Thus, 8th term of the sequence denoted as  

Substitute n= 8 in (1) ,  we get,

Thus 8th term of geometric sequence is 312500
