Answer:

3, 5, 7, 9, 11, ......

Step-by-step explanation:

To obtain the first 5 terms in the sequence substitute n = 1, 2, 3, 4, 5 into the n th term formula, that is

a(1) = 2(1) + 1 = 2 + 1 = 3

a(2) = 2(2) + 1 = 4 + 1 = 5

a(3) = 2(3) + 1 = 6 + 1 = 7

a(4) = 2(4) + 1 = 8 + 1 = 9

a(5) = 2(5) + 1 = 10 + 1 = 11
