The tenth term of an arithmetic sequence is 65 and its 15th term is 80. Is 200 a term of this sequence? |
|
Answer» To get the 15th term from the 10th term, we must add the common difference 5 times. 5 times of common difference = 80 – 65 = 15 Common difference (d) = 15/5 = 3 Dividing 65 by 3 we get the remainder as 2. Dividing 200 by 3 we get the remainder as 2. Therefore 200 is a term of this sequence. |
