find 5th term from end of the AP 17,14.11............ -40

Hey frnd here is your answer:

  • Here, a= 17 ,d = -3 , n = 5
  • We can find out the terms from last or end using,
  • Now, an= l - (n-1)d . . . . . . . . . . .{Where , l is the last term}
  • a5= -40 - (5-1)(-3)
  • a5= -40 - 4(-3)
  • a5= - 40 +12
  • a5 = - 28
  • So , Last term of the given AP is - 28.
