(4n + 3)(n + 6) so n is either -3/4 or -6
14 ! If n=12, then 12-4 is 8, plus 6 is 14
For n = 1, 2, 3, 4, 5, ... the sequence goes 4, 5, 6, 7, 8, ...
n=45

n² - 10n + 24 = 0 You need two numbers that multiply to equal 24. They have to add to equal -10. -6 times -4 is 24 -6 plus -4 is -10 Your answer is (n - 6)(n - 4).
I assume that you mean n = 3 6n + 4 = 6(3) + 4 = 18 + 4 = 22
For n = 1, 2, 3, 4, 5, ... the sequence goes 4, 5, 6, 7, 8, ...
n=45
7n+10
1+2 = 3 1+2+3 = 6 1+2+3+4 = 10 1+2+...+ N = 1/2(N+1)N if N = 50, 1+2+...+50 = 1/2 x 51 x 50 = 1275 Since 2+4+6+...+100 = 2 x (1+2+3+...+50) = 2 x 1275 = 2550
(n2 + n)/2 1+2+3+4+5+n= 15+n
2+n-3 = 6 n = 6+3-2 n= 7
n/(3/4) equal 4*n/3 4n/3=6 n=6*3/4 n=9/2
3n + 9 = 3(n + 3)
