Oh, what a happy little question! Yes, my friend, 30 tens do indeed equal 300. Just imagine each group of ten as a lovely little bundle of joy, and when you have 30 of them, you have a grand total of 300. Keep up the good work, you're doing great!
3000 30 times 100 ie 3000
30 x 100 = 3000
30 multiplied by 100 equals 3,000.
Clearly here the nth term isn't n25.
90

30 tens does not equal 3000.
6n+10
12/30 = 120/300 = 1200/3000 etc.
When n=30, 3n-1 = 89 .
