When the common difference of an arithmetic sequence is positive, will the 2nd term be greater than or less than the 1st term?

• the 2nd term will be greater than the 1st term

• the 2nd term will be less than the 1st term

• the 2nd term will be equal to the 1st term

• insufficient information without knowing the specific value of the 1st term
