+105 What is the recursive rule for the sequence?
−7.4, −21.2, −35, −48.8, −62.6, ...
A) an = an+1 − 13.8, where a1 = −7.4
B) an = an−1 + 13.8, where a1 = −7.4
C) an = an+1 + 13.8, where a1 = −7.4
D) an = an−1 − 13.8, where a1 = −7.4
+37153 a1 is the first term = -7.4
the common difference between tems is -13.8
the an th term is the previous term + the common difference, so
an = a(n-1) + (-13.8) or an= a(n-1) - 13.8
