Ano ang Arithmetic Sequence?

An arithmetic sequence is a list of numbers where consecutive terms differ by a constant value called the common difference (d). Examples include: 2, 5, 8, 11... (d=3) or 10, 7, 4, 1... (d=−3).

Pormula

nth term: aₙ = a₁ + (n−1) × d

Step-by-Step na Gabay

1nth term: aₙ = a₁ + (n−1) × d
2Sum of n terms: Sₙ = n/2 × (2a₁ + (n−1)d) = n/2 × (first + last)
3If you know any two terms and their positions, you can find d
