Per NCERT, what is the EXPLICIT rule of a sequence?
AA pictorial representation
BA formula that gives the nth term directly in terms of its position number n (e.g. tₙ = 2n − 1 for odd numbers)
CA formula that uses only the previous term
DKnowing only the first term
Answer & Solution
Correct answer: B. A formula that gives the nth term directly in terms of its position number n (e.g. tₙ = 2n − 1 for odd numbers)
Per NCERT §8.2, explicit rule = formula in n giving tₙ directly. The other options describe recursive rules or unrelated.
