Arithmetic Progressions — Key Formulas
| Formula | Expression |
|---|---|
| AP definition | Sequence where a_n - a_(n-1) = d (constant common difference) |
| nth term | a_n = a₁ + (n-1)d |
| Sum of n terms | S_n = n/2[2a + (n-1)d] = n/2(first + last) |
| Common difference | d = a₂ - a₁ (or any a_n - a_(n-1)) |
| Arithmetic mean | Between a and b: AM = (a+b)/2 |
| AP of 3 terms | Let (a-d), a, (a+d); then 3a = sum |
| AP property | For AP: a_n = (a_(n-1) + a_(n+1))/2 |
