Find the sum of first 10 even numbers.

Answer

To find the sum of the first 10 even numbers, we can follow these steps:

### Step 1: Identify the first 10 even numbers
The first 10 even numbers are:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20.

### Step 2: Use the formula for the sum of the first n even numbers
The formula for the sum of the first n even numbers is given by:
\[ \text{Sum} = n \times (n + 1) \]
where \( n \) is the number of even numbers.

### Step 3: Substitute n with 10
Since we want the sum of the first 10 even numbers, we substitute \( n = 10 \) into the formula:
\[ \text{Sum} = 10 \times (10 + 1) \]

### Step 4: Calculate the expression
Now, calculate the expression:
\[ \text{Sum} = 10 \times 11 = 110 \]

### Conclusion
The sum of the first 10 even numbers is \( 110 \).
