Problem Statement

The problem states that a squirrel is stocking up on nuts for the winter. On Monday, the squirrel brings 2 nuts, and each subsequent day of the week, it brings 1 more nut than the previous day. The task is to determine how many nuts the squirrel brings in total for the week.

Solution

To solve this problem, we can use a simple arithmetic progression formula. The formula for the sum of an arithmetic progression is:

Sum = (n/2) * (first term + last term)

In this case, the first term is 2 (the number of nuts brought on Monday), and the last term is 2 + 6 - 1 = 7 (the number of nuts brought on Sunday). The common difference between consecutive terms is 1.

So, the expression to calculate the total number of nuts brought by the squirrel for the week is:

Sum = (7/2) * (2 + 7)

To simplify the expression, we can perform the calculations step by step:

1. Calculate the sum of the first and last terms: 2 + 7 = 9. 2. Divide the sum by 2: 9 / 2 = 4.5. 3. Multiply the result by 7: 4.5 * 7 = 31.5.

Therefore, the squirrel brought a total of 31.5 nuts for the week.

Calculation Method

To calculate the value of the expression, we can follow these steps:

1. Add the first and last terms: 2 + 7 = 9. 2. Divide the sum by 2: 9 / 2 = 4.5. 3. Multiply the result by 7: 4.5 * 7 = 31.5.

Using this method, we can easily find the total number of nuts brought by the squirrel for any given week.

Please note that the result is a decimal number (31.5) because the number of nuts brought on Sunday is a fractional value.
