The coefficient of n

∙ 14y ago4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
4n-3=5 add 3 both sides 4n=8 divide by 4 both sides n=2
4n+13=1 -13 -134n=-12/4 /4n=-3
4n + 9 = -3 Now, we take away 9 from both sides 4n = -12 Now divide by 4 n = -3
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
Yes. Multiplying out the brackets on the second one: 4(n + 3) = 4×n + 4×3 = 4n + 12.
The nth term IS 4n + 3 ie 4 times n and then add 3.
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
8+4n=-4 algebra gives us 4n=-12 n=-3
4 + 4n - 12 = 4n - 8
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
2mn-4
The next term is: 15+4 = 19 The nth term is: 4n-5
4n-1 = 3
To find the equation of a sequence, you first have to look at the differences between the numbers. In this case the differences are 4, and 4. Thus the equation begins 4n. The sequence minus 4n is: 3, 3, 3 Thus the equation in its entirety is that the value of the term in position n is 4n+3
4n = 48 4n/4 = 48/4 (Divide by 4 on both sides and then cancel) n = 12
