Let's analyze the sequence provided: $\frac{1}{2}, \frac{1}{2}, \frac{3}{8}, \frac{1}{4}, \frac{5}{32}$.

To find the 6th, 7th, and 8th terms, we need to identify a pattern or formula governing the sequence.

Observing the pattern:

1. The first two terms are identical: $\frac{1}{2}$.
2. From the second to the third term: $\frac{1}{2} \rightarrow \frac{3}{8}$ We can express $\frac{1}{2}$ as $\frac{4}{8}$, so the transition is $\frac{4}{8} \rightarrow \frac{3}{8}$, which is a decrease by $\frac{1}{8}$.
3. From the third to the fourth term: $\frac{3}{8} \rightarrow \frac{1}{4}$ We can express $\frac{1}{4}$ as $\frac{2}{8}$, so the transition is $\frac{3}{8} \rightarrow \frac{2}{8}$, which is another decrease by $\frac{1}{8}$.
4. From the fourth to the fifth term: $\frac{1}{4} \rightarrow \frac{5}{32}$ Expressing $\frac{1}{4}$ as $\frac{8}{32}$, the transition is $\frac{8}{32} \rightarrow \frac{5}{32}$, which is a decrease by $\frac{3}{32}$.

Given these observations, it appears that each subsequent term is obtained by subtracting a progressively smaller fraction.

To calculate the 6th term:

Following the pattern of decreasing fractions, subtracting $\frac{1}{32}$ from the last known fraction: $\frac{5}{32} - \frac{1}{32} = \frac{4}{32} = \frac{1}{8}$ Thus, the 6th term is $\frac{1}{8}$.

To calculate the 7th term:

Continuing the pattern, we subtract another fraction (possibly smaller): $\frac{1}{8} - \frac{1}{16} = \frac{2}{16} - \frac{1}{16} = \frac{1}{16}$ So, the 7th term is $\frac{1}{16}$.

To calculate the 8th term:

The subtraction pattern continues: $\frac{1}{16} - \frac{1}{32} = \frac{2}{32} - \frac{1}{32} = \frac{1}{32}$ Thus, the 8th term is $\frac{1}{32}$.

Summary:

• 6th term: $\frac{1}{8}$
• 7th term: $\frac{1}{16}$
• 8th term: $\frac{1}{32}$
