What are the first four terms of the sequence given by the formula below an 2n 4?

To find the first four terms of the sequence defined by the formula a_n = 2n + 4, we simply substitute the values of n from 1 to 4 into the formula.

1. For n = 1:
a₁ = 2(1) + 4 = 2 + 4 = 6

2. For n = 2:
a₂ = 2(2) + 4 = 4 + 4 = 8

3. For n = 3:
a₃ = 2(3) + 4 = 6 + 4 = 10

4. For n = 4:
a₄ = 2(4) + 4 = 8 + 4 = 12

Thus, the first four terms of the sequence are: 6, 8, 10, and 12.
