By the condition of the problem, the first term b1 of this geometric sequence is 4, and the denominator q of this progression is 1/2.

Knowing the first term b1 and the denominator q of this progression, we find the second term of this progression:

b2 = b1 * q = 4 * (1/2) = 4/2 = 2.

Knowing the second term b2 and the denominator q of this progression, we find the third term of this progression:

b3 = b2 * q = 2 * (1/2) = 2/2 = 1.

Answer: b3 = 1.
