Solving the Arithmetic Linear Equation: How to Use l = a + (n – 1) · d to Find 9995 – 1000 Under a Common Difference of 5
Mathematics is not only about numbers—it’s also about patterns, relationships, and solving equations. One powerful tool in algebra is the linear formula:
l = a + (n – 1)·d
This equation is widely used in sequences, progressions, and real-world applications. Whether you’re analyzing sequences or solving for unknowns, understanding how to apply this formula can save time and improve problem-solving accuracy.
Understanding the Equation
The formula
l = a + (n – 1)·d
describes the last term (l) of a first-term arithmetic sequence, where:
- a = starting term
- d = constant difference between consecutive terms
- n = number of terms
- l = the final term in the sequence
Understanding the Context
This formula is ideal for calculating values in arithmetic sequences without listing every term—especially useful when dealing with large sequences like 9995.
Applying the Formula to Solve:
9995 = 1000 + (n – 1) · 5
Let’s walk through the steps to solve for n, making it a perfect practical example of how this linear relationship works.
Key Insights
Step 1: Identify known values
From the equation:
- a = 1000 (starting value)
- d = 5 (common difference)
- l = 9995 (last term)
Step 2: Plug values into the formula
Using:
9995 = 1000 + (n – 1) · 5
Subtract 1000 from both sides:
9995 – 1000 = (n – 1) · 5
→ 8995 = (n – 1) · 5
Step 3: Solve for (n – 1)
Divide both sides by 5:
8995 ÷ 5 = n – 1
1799 = n – 1
Step 4: Solve for n
Add 1 to both sides:
n = 1799 + 1 = 1800

Result: There are 1800 terms in the sequence starting at 1000 with a common difference of 5, ending at 9995.
Why This Formula Matters
Using l = a + (n – 1)·d removes guesswork. It helps solve problems in:
- Financial planning (e.g., savings growth with fixed increments)
- Computer science (calculating array indices or loop iterations)
- Real-world sequence modeling
It’s a concise way to analyze linear growth patterns efficiently.
Final Thoughts
Mastering linear equations like l = a + (n – 1)·d makes tackling sequences faster and more intuitive. In the example of 9995 = 1000 + (n – 1)·5, we didn’t just find a number—we unlocked a method to solve similar problems quickly. Whether you’re a student, teacher, programmer, or hobbyist, understanding this pattern empowers smarter, sharper problem-solving every day.
