Question

In the nth term formula \( t_{n} = a + (n - 1)d \), what does the symbol \( d \) represent?

Options

• First term

• Common difference

• nth term

• Term number

Answer 1

In the formula \( t_{n} = a + (n - 1)d \), the symbols stand for: \( a \) = first term, \( d \) = common difference, \( n \) = term number, and \( t_{n} \) = nth term. Thus \( d \) is the common difference.
