Understanding the Context
The sum of an arithmetic sequence is 1150. First term is 10, common difference is 5. How many terms?
This is not just a routine calculation—it’s a gateway to understanding mathematical reasoning behind real-life patterns. While many view arithmetic sequences through a purely academic lens, their applications appear in budgeting, project planning, and digital algorithms fundamental to modern life. With many users now seeking practical math skills for personal finance, data literacy, or programming basics, questions like this reflect a demand for clear, accessible problem-solving techniques. The combination of known first term and common difference invites learners to apply a standard formula efficiently—preserving accuracy while building confidence.
3. How the Sum of This Arithmetic Sequence Actually Works
At its core, an arithmetic sequence follows a consistent step pattern. With a first term of 10, each subsequent term increases by 5:
10, 15, 20, 25, …
The formula to find how many terms (n) produce a total sum of 1150 is rooted in arithmetic series convergence:
Sum = (n/2) × (2a + (n – 1)d)
Where:
a = first term (10)
d = common difference (5)
Sum = 1150

Plugging in values:
(n/2) × (2×10 + (n – 1)×5) = 1150
Simplify:
(n/2) × (20 + 5n – 5) = 1150
(n/2) × (5n + 15) = 1150
Multiply both sides by 2:
n(5n + 15) =
