A geometric sequence starts with 2, and each term is 1.5 times the previous term. What is the sum of the first 5 terms? - Decision Point

Understanding the Context

Right now, conversations around compound growth are trending across financial planning, education, and digital learning platforms. This particular sequence—starting at 2 and multiplying by 1.5—mirrors how small consistent inputs can lead to meaningful gains over time. Whether tracking ROI, modeling growth, or teaching foundational math, its predictable rhythm offers clarity. In mobile-first environments, users browsering for insights on personal finance or career trends often encounter recurring number patterns like this—making it a natural fit for Discover search intent.

Even without explicit context, the sequence appears in budgeting apps, financial simulations, and STEM outreach, proving its real-world relevance. As users seek data literacy tools to interpret growth and change, this sequence—simple, predictable, and tangible—fills a clear educational gap.

How It Works: Calculating the First Five Terms

To find the sum of the first five terms, start with the initial value and apply the growth factor iteratively.

• Term 1: 2
• Term 2: 2 × 1.5 = 3
• Term 3: 3 × 1.5 = 4.5
• Term 4: 4.5 × 1.5 = 6.75
• Term 5: 6.75 × 1.5 = 10.125

Key Insights

Adding these together:
2 + 3 + 4.5 + 6.75 + 10.125 = 26.375

Thus, the sum of the first five terms is 26.375.

This method shows how each step builds directly on the last, reflecting the essence of geometric progression—exponential growth rooted in consistent multiplication. Even without advanced math, breaking it down clearly helps users visualize and internalize how compounding works.

Common Questions About the Sum of This Sequence

H3: How Accurate Is This Calculation?
The result of 26.375 is correct, calculated precisely using sequential multiplication. Because each term depends on the prior, rounding at intermediate steps may introduce small discrepancies, but full precision matches exactly. Tools and calculators confirm the total, ensuring reliability for informed decision-making.
