Answer 2

Problem Analysis

We are given that a row of trees was planted in a park. After one year, an additional tree was planted between every two neighboring trees. The same process was repeated after another year, resulting in a total of 1197 trees. We need to determine the initial number of trees.

Solution

Let's assume that the initial number of trees in the row is x.

After the first year, an additional tree is planted between every two neighboring trees. This means that the number of trees doubles. So after the first year, there are 2x trees.

After the second year, the same process is repeated. An additional tree is planted between every two neighboring trees, resulting in the number of trees doubling again. So after the second year, there are 4x trees.

According to the problem statement, after the second year, there are 1197 trees. Therefore, we can set up the following equation:

4x = 1197

To find the value of x, we can solve this equation:

x = 1197 / 4

Let's calculate the value of x:

x = 1197 / 4 = 299.25

Since the number of trees must be a whole number, we can conclude that the initial number of trees was 299.

Answer

The initial number of trees in the row was 299.
