Frequently Asked Questions

What is an arithmetic sequence?

A sequence where each term differs by a constant (common difference). Formula: aₙ = a₁ + (n-1)d.

What is a geometric sequence?

A sequence where each term is multiplied by a constant (common ratio). Formula: aₙ = a₁ × r^(n-1).

How do I find the pattern in a sequence?

Check differences between consecutive terms for arithmetic sequences, ratios for geometric sequences, or second differences for quadratic patterns.

Why is math important?

Math develops problem-solving skills, logical thinking, and helps understand patterns in science, finance, and daily life.

How can I improve accuracy?

Double-check work, use estimation to verify reasonableness, understand concepts deeply, and practice regularly.

What if I get different results?

Verify input values, check calculation steps, ensure correct formula usage, and consider rounding differences.

How do I know which method to use?

Identify knowns and unknowns, understand the relationships between variables, and match to appropriate formulas.
