To find b5, we can use the formula for the nth term of a geometric sequence:
bn = b1 * q^(n-1)
Plugging in the values we have:b1 = 500q = 1/5n = 5
b5 = 500 (1/5)^(5-1)b5 = 500 (1/5)^4b5 = 500 * (1/625)b5 = 500/625b5 = 0.8
Therefore, b5 = 0.8.

Plugging in the values we have:
b1 = 500
q = 1/5
n = 5
b5 = 500 (1/5)^(5-1)
b5 = 500 (1/5)^4
b5 = 500 * (1/625)
b5 = 500/625
b5 = 0.8
Therefore, b5 = 0.8.
