3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
The nth term of this sequence is 3n + 4
Let the number be N, then (3/4 of N) - 4 = (1/2 of N) or (3N/4) - 4= N/2 or 3N - 16 = 2N or 3N - 2N = 16 N = 16 Verification: When 4 is subtracted from 3/4 of 16 you get (12 - 4) = 8 which is equal to 1/2 of 16 which is 8 also
2+3n+2+9n would equal 4+12n after adding all like numbers.
When n = 4, 3n = 3*4 = 12
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
3n2-8n+4 = (3n-2)(n-2) when factored
The nth term of this sequence is 3n + 4

3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
They are two terms of an algebraic expression in the form of 45-3n
When n = 4, 3n = 3*4 = 12
3n+2+3n+2=6n+4
3n^4 divided by 3n^3 = n
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
