AI explanation

To find the first two terms of the sequence, substitute n = 1 and n = 2 into the given expression 5n + 4. For n = 1, the calculation is 5(1) + 4, resulting in the first term of 9. For n = 2, the calculation is 5(2) + 4, resulting in the second term of 14. The first two terms are 9, 14.
