Answer:
aₙ = (-1)^(n+1) * 2^(7 - n/2)
Explanation:
Using this formula, we can find any term in the sequence by substituting the desired value of n. For example, to find the 6th term in the sequence, we would substitute n = 6 into the formula:
a₆ = (-1)^(6+1) * 2^(7 - 6/2)
= (-1)^7 * 2^(7 - 3)
= -1 * 2^4
= -16
