Answer :
Final answer:
The explicit formula for the arithmetic sequence is an = -38.4 + (n - 1)(-19.7).
Explanation:
The explicit formula for an arithmetic sequence is given by the formula:
aₙ = a₁ + (n - 1)d
Where aₙ is the term you want to find, a₁ is the first term of the sequence, n is the position of the term in the sequence, and d is the common difference between the terms.
In this case, the first term a₁ = -38.4 and the common difference d = -19.7. So the explicit formula for this arithmetic sequence is:
aₙ = -38.4 + (n - 1)(-19.7)
