To find the 7th term in the sequence defined by the formula a_n = 30 + 4n, we need to substitute n with 7.
The formula for the nth term can be rewritten specifically for this case:
a_7 = 30 + 4(7)Now, let’s calculate:
- First, calculate the multiplication: 4 x 7 = 28.
- Next, add this result to 30: 30 + 28 = 58.
Therefore, the 7th term in the sequence is 58.
