Watch how to sign 'arithmetic sequence' in American Sign Language.

An arithmetic sequence has a as first term and 2 d as common difference, ie, a a+2 d, a+4 d, …. The sum of the first 50 terms is T. Another sequence, with first term a+d, and common difference 2 d, is combined with the first one to produce a new arithmetic sequence. Let the sum of the first 100 terms of the new combined sequence be S. If 2 T+200=St find d. | Numerade
