Welcome to our Sum of a Linear Number Sequence Calculator! This powerful tool is designed to make computing the sum of arithmetic sequences easy and efficient. Arithmetic sequences, characterized by a constant difference between consecutive terms, are commonly encountered in mathematics and various real-world applications. In this article, you will learn how to use our calculator, understand the underlying formulas, and explore numerous examples to solidify your understanding.

How to Use

Using our sum calculator is straightforward:

1. Input the first term of your sequence.
2. Enter the common difference between the terms.
3. Specify the total number of terms you wish to include in the sequence.
4. Click the Calculate button to obtain the sum of the sequence.

For an even smoother experience, our intuitive user interface allows you to visualize the sequence while you make your calculations.

Formula

The fundamental formula used in calculating the sum of a linear number sequence is:

S = n/2 * (2a + (n – 1)d)

Where:

• S = sum of the sequence
• n = number of terms
• a = first term of the sequence
• d = common difference

This formula facilitates the calculation of the sum without needing to manually add every term in the sequence, significantly speeding up your computations.

Example Calculation

Let’s say we want to calculate the sum of the first 10 terms in the sequence where the first term is 2 and the common difference is 3:

First term (a): 2

Common difference (d): 3

Number of terms (n): 10

Substituting into the formula:

S = 10/2 * (2*2 + (10 – 1)*3)

S = 5 * (4 + 27)

S = 5 * 31 = 155

Thus, the sum of the first 10 terms in the sequence is 155.
