Answer:

B

Step-by-step explanation:

firstly as we know that,

nth term of an A.P. is n= a1 + (n-1)d

here d is -3 so, A1 = 1-(-3) = 4

so, 5th term = 4 + ( 5-1)( -3) = 4 + 4(-3) = 4 - 12 = -8

so the answer is -8 which is option B.

Hope this answer helps. I got a little help from my tutors on Gauthmath app which is really good. you can check it out too. :)
