GCF(4n, 5n) = n
5n-2+2=4n 5n=4n n=0
4n - 5n is biger and no it not
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
The GCF is 5n.
The GCF is 5n
In the equation 5n-11=4n+20, n is equal to 31.
it equals -4n
-2n

4n
The series is a(n) = 4n² +5n. . . and this is the general formula which also gives the nth term. When n = 1, 4n² + 5n = 4*1 + 5*1 = 9 When n = 2, 4n² + 5n = 4*4 + 5*2 = 26 . . .and so on When n = 5, 4n² + 5n = 4*25 + 5*5 = 125. The series can be determined using the Difference Technique. A second difference of 8 gives the first term 4n². . . . as a 2nd difference of 2 equates to n². After applying this to the original series, the revised series produces a 1st difference of 5, hence 5n.
