Understanding the Context
This problem is more than a textbook puzzle. In an era where data literacy drives decision-making, learners and professionals alike are seeking clear, reliable answers to foundational math questions. The specific setup—first term 4, common difference 4, total sum 180—mirrors real-world accumulation patterns. Whether tracking progress, analyzing investment growth, or modeling steady increases, recognizing how these elements fit together reveals powerful insights. Meanwhile, educators emphasize clean, logical problem-solving to build confidence—skills that extend well beyond high school classrooms and into professional problem-solving across industries in the U.S.
How The sum of the first n terms of an arithmetic sequence is 180, with first term 4 and common difference 4. What is n?—A Clear Breakdown
To find n, we use the standard formula for the sum of the first n terms of an arithmetic sequence:
Sₙ = (n/2) × [2a + (n – 1)d]
Where Sₙ is the total sum, a is the first term, and d is the common difference.
Plugging in the values:
Sₙ = (n/2) × [2(4) + (n – 1)(4)]
= (n/2) × [8 + 4(n – 1)]
= (n/2) × [8 + 4n – 4]
= (n/2) × (4n + 4)
= (n/2) × 4(n + 1)
= 2n(n + 1)

Key Insights
We’re told Sₙ = 180, so:
2n(n + 1) = 180
Divide both sides by 2:
n(n + 1) = 90
Now solve the quadratic:
n² + n – 90 = 0
Factoring:
(n + 10)(n – 9) = 0
Solutions: n = –10 or n = 9
Since n must be a positive integer, the answer is:
n = 9
