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.
