Answer:

hey frnd here is your answer

Step-by-step explanation:

as per your question a=7 (first term) and common difference d= -4

Formula is a+(n-1)(d)

we want a+(n-1)(d) =. -89

by putting the values of a and d we get n=25

so frnd your answer is 25th term

solving process

a+(n-1)(d) = -89

7+(n-1)(-4)=-89

7-4n+4= -89

4n=100

n=25

so frnd 25th term is -89

I hope you get your answer
