A 1 = 3, a (n + 1) = 3an - 2 fast

A 1 = 3, a (n + 1) = 3an - 2 fast

Power of A1 = 3a2 = 3a1-2 = 3 * 3 - (power of 3-1) - A3 = 3a2-2 = 3 * (3a1-2) - 2 = 9a1-8 = 3 * 3 - (power of 3-1) A4 = 3a3-2 = 3 * (3 * (3a1-2) - 2 = 27a1-26 = 3 * 3 - (power of 3-1)... Power of an = 3 - (power of 3 - (power of 3-1) - 1)
