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
