Question

2 3n - 1 is divisible by 7

Answer 1

If we take 0,1,2,3,4,5.........like this then solve it by by applying the data one by one then start take 0 according to question 230 -1=229 which is not divisible by 7 then we take 1 according to question 231-1=230 which is not divisible by 7 then we take 2 according to question 232-1=231 which is divisible by 7 so the value of 'n' is 2
