Find Nth Term (n)

Arithmetic Progression (AP): Each term increases by a constant difference. Formula: aₙ = a + (n-1)d

Geometric Progression (GP): Each term is multiplied by a constant ratio. Formula: aₙ = a × r^(n-1)

Fibonacci: Each term is the sum of the two preceding terms. Sequence: 0, 1, 1, 2, 3, 5, 8, 13...

Square Numbers: Perfect squares (1, 4, 9, 16, 25...)

Cube Numbers: Perfect cubes (1, 8, 27, 64, 125...)

Triangular Numbers: Sum of first n natural numbers (1, 3, 6, 10, 15...)

Prime Numbers: Natural numbers with exactly two divisors (2, 3, 5, 7, 11...)
