Answer:

d. (5n-9)

Step-by-step explanation:

  • First term = -4
  • Common difference = 1-(-4)=1+4=5
  • Formula used: L =a+(n-1)d

where, L is the last term;

a is the first term ;

n is the number of terms;

and d is the common difference.

  • L = -4+(n-1)5= -4+5n-5 = 5n-9

Therefore, the last term is (5n-9).
