Answer:
A=14, d=-3,l=-1
l=a+(n-1)d
-1=14+(n-1)(-3)
-15÷(-3)=(n-1)
n-1=5
n=6
So it's 6th term will be -1.

Answer:
given : a = 14, d = 11 - 14 = -3, aₙ = -1
to find n
aₙ = a + (n-1) d
=> -1 = 14 + [(n - 1 ) (-3) ]
=> -1 = 14 + ( -3n + 3)
=> -1 = 14 - 3n + 3
=> 3n = 14 + 3 + 1
=> 3n = 18
n = 6
6th term is - 1 Answer
