Final answer:
In a geometric progression (G.P), if the second term is 8 and the common ratio is positive, the first term can be found by dividing 8 by the common ratio.
Step-by-step explanation:
A geometric progression (G.P) is a sequence of numbers where each term after the first is found by multiplying the previous term by a constant called the common ratio. In this question, the second term is given as 8, so we can write the sequence as:
1st term: a
2nd term: 8
3rd term: 8r
4th term: 8r^2
5th term: 8r^3
6th term: 8r^4
Since the common ratio is positive, we can assume that r > 1. To find the value of the first term, we need to find the value of r. Let's use the given information and solve for r:
8 = ar
r = 8/a
Now, we can substitute the value of r in the equations for the first six terms and find their values.
