Is 2018 a term of the sequence 5,11,17....?

Answer»

No 2018 is not a term of the sequence.


let, the NUMBER of term of 2018 be N.
therefore,
ACCORDING to the question,
5+(n-1)6=2018
=>6(n-1) = 2013
=> 6n-6 =2013
=> 6n = 2019
=> n = 2019/6

it is a fraction. the number of term can not be fraction.


this is the reason for this question.
