a7=−1
a subscript 7 baseline equals negative 1

Answer 1

To find the seventh term of the sequence using the explicit formula \( a_n = 4 - 3n \), we plug in \( n = 7 \):

\[ a_7 = 4 - 3(7) \] \[ a_7 = 4 - 21 \] \[ a_7 = -17 \]

So, the seventh term \( a_7 \) is \( -17 \).

The correct response is:

a7=−17
