Use the explicit formula an=4−3n

Question

to find the seventh term of the arithmetic sequence.

Answer 1

To find the seventh term of the sequence given by the explicit formula \( a_n = 4 - 3n \), you need to substitute \( n = 7 \) into the formula.

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

Calculating the expression:

\[ a_7 = 4 - 21 \]

\[ a_7 = -17 \]

So, the seventh term of the sequence is \( \boxed{-17} \).
