Answer:

0.004

Explanation:

The first term for this geometric series, a1, is 40,000

The common ratio for this geometric series, r, is 0.1

The eight term for this geometric series, a8, is given by the equation a1*r^7

a8=40000*0.1^7

=0.004

Answer:

a8 = 0.004

Explanation:

Q is abt a geometric series given by the eqn: an = a1*r^(n-1)

given a1 = 40000, r = 0.1

an = 40000*(0.1)^(n-1)

a8 = 40000*(0.1)^(8-1)

= 40000*(0.1)^7

= 0.004
