Final answer:
The first five terms of the sequence are 7, 9, 11, 13, and 15.
Step-by-step explanation:
The sequence is defined by the formula an = 2n + 5. To find the first five terms of the sequence, we substitute the values of n from 1 to 5 into the formula:
- a1 = 2(1) + 5 = 7
- a2 = 2(2) + 5 = 9
- a3 = 2(3) + 5 = 11
- a4 = 2(4) + 5 = 13
- a5 = 2(5) + 5 = 15
Therefore, the first five terms of the sequence are 7, 9, 11, 13, and 15.
