Answer:
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
