If n approaches +∞, then the elements of the progression approach:

This problem is about a geometric progression. We are given that the absolute value of the common ratio |q| is less than 1, specifically |q| = 1/4 < 1.

In a geometric progression, if the absolute value of the common ratio |q| is less than 1, then as n (the term number) approaches infinity, the terms of the progression approach 0.

The given terms b₅ = 1/16, b₆ = 1/64, and b₇ = 1/256 are consistent with a geometric progression where q = 1/4. For example, b₆ = b₅ * q = (1/16) * (1/4) = 1/64.

Therefore, as n approaches +∞, the elements of the progression tend towards 0.

Answer: 0
