What is the general formula for an arithmetic series?

• Sn = a1 + (n-1)d

• Sn = n * (a1 + an)

• Sn = n/2 * (a1 + an)

• Sn = n * d

In the arithmetic series formula, what does 'd' represent?

• The first term

• The last term

• The common difference

What is the formula for a geometric sequence?

• an = a1 + (n-1)d

• an = a1 + n

• an = a1 / r^(n-1)

What is the formula for the nth term of an arithmetic sequence?

• an = n * d

• an = a1 * r^(n-1)

• an = a1 + (n-1)d

• an = a1 + n

What is the sum of the first n terms of an arithmetic series?

• Sn = a1 + an

• Sn = n/2 * (2a1 + (n-1)d)

• Sn = n * d

• Sn = n * (a1 + an)

In the formula Sn = n/2 * (a1 + an), what does 'an' represent?
