Oh, dude, you want me to do math? Like, okay, fine. So, 3n - 18 is like, just a fancy way of saying 3 times some number minus 18. That's it. Math is so serious, man, but hey, it's 3n - 18.
Let n be the number, then: 1/n - 1/3n = 1/6 Solve the subtraction on the left: 1/n - 1/3n = 3/3n - 1/3n = 2/3n But we know this is 1/6, thus: 2/3n = 1/6 ⇒ 3n = 12 ⇒ n = 4 Thus the number is 4.
The first, second, third, fourth, and fifth terms of 3n - 7 are as follows:1: -42: -13: 24: 55: 8
One possible answer is Un = 3n - 1 for n = 1, 2, 3, ...
3n + 8
The 'n'th term is [ 4 - 3n ].
