I assume you mean the 5th term is 5.
You don't even have to find the 1st term, a; just start at 5 and go backwards, adding 3 each time:
17,14,11,8,5
If you want to do it algebraically, of course, just realize that the 5th term is
a+4d = a+4(-3) = 5
a-12 = 5
a = 17

Answer: (given) an = 5 and difference = -3
a⁵ = a + 4 d
5 = a + 4(-3)
5 = a + (-12)
5 = a - 12
12 + 5 = a
a = 17
Ans- a= 17
Fifty term of A.P Is 17
a⁵ = a + 4 d
5 = a + 4(-3)
5 = a + (-12)
5 = a - 12
12 + 5 = a
a = 17
Ans- a= 17
