Write the first five terms of each of the sequences. whose nth terms are an =



Answer :


an =
Substituting n = 1, 2, 3, 4 and 5 we get

a1 = (2 x 1 - 3)/6 = -1/6

a2 = (2 x 2 - 3)/6 = (4 - 3)/6 = 1/6

a3 = (2 x 3 - 3)/6 = (6 - 3)/6 = 3/6 = ½

a4 = (2 x 4 - 3)/6 = (8 - 3)/6 = 5/6

a5 = (2 x 5 - 3)/6 = (10 - 3)/6 = 7/6

Therefore the first term is –1/6, 1/6, ½, 5/6 and 7/6.
