The nth term of a sequence is 3n + 5
Scrat [10]

Answer:

5th term is 20

6th term is 23

4th term is 17

Step-by-step explanation:

So what you need to do is put the number that you are trying to get in the space of n. So if you want the 5th term, put the number in the n space. So it reads 3 5+ 5

Then times the 3 and the 5 that are next to each other that you put in the space of n

15+5

Then add them together so it’s 20

Hope that help.

If f(x)=2x-1+3 and g(x)=5x-9, what is (f-g)(x)?
dangina [55]

Answer:

\large\boxed{(f-g)(x)=-3x+11}

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)\\\\f(x)=2x-1+3=2x+2\\g(x)=5x-9\\\\\text{Substitute:}\\\\(f-g)(x)=(2x+2)-(5x-9)\\\\=2x+2-5x-(-9)\\\\=2x+2-5x+9\qquad\text{combine like terms}\\\\=(2x-5x)+(2+9)\\\\=-3x+11
