Hey mate!
Here is yr answer....
__________________________
Given, AP is...
2 , 9 , 16 .........
Here,
a = 2 , d = 9-2 = 7 , an = 600
From nth term formula,
an = a+(n-1)d
600 = 2 +(n-1)7
600 = 2+ 7n -7
600 = 7n -5
7n = 600+5
7n = 605
n = 605/7
Since, n value is in the rational form
Therefore, 600 is not a term of the series.
