Question

Which statement does NOT describe the explicit arithmetic formula?

The explicit arithmetic formula can easily find a term far into a sequence.

The explicit arithmetic formula adds the common difference to the previous term.

In the explicit arithmetic formula,
represents the first term in the sequence.

The explicit arithmetic formula has a common difference.

Answer 1

"The explicit arithmetic formula adds the common difference to the previous term."

Explanation: That describes the recursive form a_n = a_{n-1} + d. The explicit formula is a_n = a_1 + (n−1)d, which gives any term directly (and includes the first term and common difference).
