Find the first four terms of sequence represented by the expression.

3n+5

The first four terms of the sequence represented by the expression 3n + 5 would be:

1. When n = 1: 3(1) + 5 = 3 + 5 = 8
2. When n = 2: 3(2) + 5 = 6 + 5 = 11
3. When n = 3: 3(3) + 5 = 9 + 5 = 14
4. When n = 4: 3(4) + 5 = 12 + 5 = 17

So, the first four terms of the sequence are 8, 11, 14, 17.
