Question
Find the missing terms of each geometric sequence. (Hint: The geometric mean of the first and fifth terms is the third term. Some terms might be negative.)2.5, $\quad$,$\quad$,$\quad$,$202.5, \ldots$
Step 1
5 and the fifth term as 202.5. We know that in a geometric sequence, each term is the product of the previous term and a constant ratio (r). Therefore, we can write the fifth term as $2.5 \cdot r^4 = 202.5$. Show more…
