Answer:
Step-by-step explanation:-227 is in The sequence
13,7,1,-5,-11,.....
First term=a=13
Common difference=d=7-13=-6
Checking if -227 is in The sequence
using the formula
Tn=a+dx(n-1)
-227=13+(-6)x(n-1)
-227=13-6n+6
collect like terms
6n=13+6+227
6n=246
Divide both sides by 6
6n/6=246/6
n=41
Therefore -227 is the 41ist term Of The sequence
