To find the first 5 terms of the sequence defined by \( y_n = -5n - 5 \), we will evaluate the equation for \( n = 1, 2, 3, 4, 5 \).
1. For \( n = 1 \):
\[
y_1 = -5(1) - 5 = -5 - 5 = -10
\]
2. For \( n = 2 \):
\[
y_2 = -5(2) - 5 = -10 - 5 = -15
\]
3. For \( n = 3 \):
\[
y_3 = -5(3) - 5 = -15 - 5 = -20
\]
4. For \( n = 4 \):
\[
y_4 = -5(4) - 5 = -20 - 5 = -25
\]
5. For \( n = 5 \):
\[
y_5 = -5(5) - 5 = -25 - 5 = -30
\]
So, the first 5 terms of the sequence are:
\[
-10, -15, -20, -25, -30
\]
Thus, the correct response is:
**-10, -15, -20, -25, -30**
1. For \( n = 1 \):

Thus, the correct response is:
**-10, -15, -20, -25, -30**
