if you are doing the "pattern N soloution" it is like a pattern. ex.) 2,4,6,8... you take how much they're adding (2) and that is your first number, you add N for your other #'s you'd multiply it by.(2n) then you subtract the first # in your equasion (2) from the first # in the pattern (2) so 2- 2 = 0 therefore, your anwser would be 2n + 0= _
It is the inequality: N + 2 <= 1.

perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.
If we are to find the product of 5 and m and n/2 (which is half of n), we have: 5 times m times n/2 = 5 x m x n/2 = 5mn/2
y = x2 + 2mx + n complete the square y + m2 = x2 + 2mx + m2 + n = (x + m)2 + n (x + m)2 = y + m2 - n x + m = √(y + m2 - n) x = -m + √(y + m2 - n)
2 plus n is the true one, but 1 plus n is not?
2 plus 2 plus n equals 6 n equaling 2
(n2 + n)/2 1+2+3+4+5+n= 15+n
if (n%2==0) sum=n/2*(n+1); else sum=(n+1)/2*n;
They have n in common.
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
n^2 + n
n = 28
3^n+2+3^n = 6^n+2 *'to the power of' can be represented with this symbol ^ .
If the question means solve 1+2+...+60 then 1+2+...+n = n(n+1)/2 for any integer n>0 So for n= 60 the sum is 60*61/2 = 30*61 = 1830

n + 17 = 2 n = 2 - 17 n = -15
