If two arithmetic sequences 5,8,11. And 3,7,11. Have 100 terms, how many of them are the same

If two arithmetic sequences 5,8,11. And 3,7,11. Have 100 terms, how many of them are the same

The tolerance of the first arithmetic sequence is 3, the tolerance of the second arithmetic sequence is 4, and the least common multiple is 12. Therefore, each sequence begins with the first identical term, and each addition of 12 has one identical term
And the first same term is 11, so the general formula of the same term is 12n-1
The general formulas of the two sequences are 3N + 2 and 4N-1, and their 100th terms are 302 and 399 respectively
So the public item 12n-1
