Which recursive sequence would produce the sequence 9,−32,91,… ?a1=9 and an=−3an−1−5a1=9 and an=−4an−1+4a1=9 and an=−5an−1−3a1=9 and an=4an−1−4
Q. Which recursive sequence would produce the sequence 9,−32,91,… ?a1=9 and an=−3an−1−5a1=9 and an=−4an−1+4a1=9 and an=−5an−1−3a1=9 and an=4an−1−4
Identify First Term: Identify the first term of the sequence.The first term given for all options is a1=9.
Calculate Second Term: Use the second option to calculate the second term.The second option is an=−4an−1+4. Let's calculate a2 using a1=9:a2=−4×a1+4=−4×9+4=−36+4=−32.This matches the second term of the sequence.
Calculate Third Term: Use the second option to calculate the third term.Now, let's calculate a3 using a2=−32:a3=−4×a2+4=−4×(−32)+4=128+4=132.This does not match the third term of the sequence (91).
