Correct option is (B) -82
Given: A.P is \(20,17,14,11, \ldots\)
Here, first term \((a)=20\)
Common difference \((d)=17-20=-3\)
\(n^{\text {th}}\) term is given by,
\(a_{n}=a+(n-1) d\)
Put \(n = 35\)
\(a_{35} = 20 + (35 - 1) (-3)\)
\(=20 + (34) (-3)\)
\(= 20 - 102\)
\(= -82\)
The 35th term of the A.P. \(20,17,14,11, \ldots\) is -82.
