Solution

The correct option is B 7th Formula to find nth term of arithmetic progression is tn=a1+(n−1)d where, 'a1' is the first term, 'd' is the common difference, 'n' is the number of terms, 'tn' is the nth term. Given, a1 = 12 and d = -2. Let the term of the AP which is equal to 0 be the nth term . ∴ a1+(n−1)d=0 12+(n−1)(−2)=0 12+2−2n=0 n=7 Hence, the value of 7th term will be 0.
