Understanding This Calculator
Arithmetic Progression Formulas
An AP is a sequence where the difference between consecutive terms is constant.
nth Term (aₙ) = a + (n-1)d
Sum (Sₙ) = n/2 × [2a + (n-1)d]
Example 1
2, 5, 8, 11... (a=2, d=3)
- 10th Term: 2 + (10-1)3 = 2 + 27 = 29
- Sum of 10 terms: 10/2 × [4 + 27] = 5 × 31 = 155
Example 2
10, 8, 6, 4... (a=10, d=-2)
- 5th Term: 10 + (4)(-2) = 10 - 8 = 2
How to Use
- Enter first term (a).
- Enter common difference (d).
- Enter number of terms (n).
