an = (2n + 1)/2n
a₁ = (2 * 1 + 1)/(2 * 1) = (2 + 1)/2 = 3/2 = 1 1/2 = 1,5
a₂ = (2 * 2 + 1)/(2 * 2) = (4 + 1)/4 = 5/4 = 1 1/4 = 1,25
a₃ = (2 * 3 + 1)/(2 * 3) = (6 + 1)/6 = 7/6 = 1 1/6 = 0,1(6)
a₄ = (2 * 4 + 1)/(2 * 4) = (8 + 1)/8 = 9/8 = 1 1/8 = 0,125
a₅ = (2 * 5 + 1)/(2 * 5) = (10 + 1)/10 = 11/10 = 1 1/10 = 1,1
