What is n divided by 2?
It is n/2.
How do you solve n 2 n n n?
2 N cubed (3)
In maths what are the three consecutive even numbers that have a sum of forty two?
The numbers are 12, 14 and 16. Let the numbers by n - 2, n and n + 2, then (n - 2) + n + (n + 2) = 3n = 42 : n = 14 so n - 2 = 12 and n + 2 = 16.
What multiplies to -8 and adds to 7?
-1
How many bit strings of length n are palindromes?
If n is even then number of palindromes is 2^(n/2). If n is odd then number of palindromes is 2*2^[(n-1)/2].
Evaluate the expression f left parenthesis n plus 2 right parenthesis minus f left parenthesis n right paren given that f left paren n right paren equals 1 over 2 n left paren n plus 2 right paren?
A very good try, but f(n) is still ambiguous. I assume you mean f(n) = 1/2*n*(n+2) and not 1/[2*n*(n+2)] Then f(n+2) - f(n) = 1/2*(n+2)*(n+2+2) - 1/2*n*(n+2) = 1/2*(n+2)*(n+4) - 1/2*n*(n+2) = 1/2*(n+2)*{(n + 4) - n} = 1/2*(n+2)*4 = 2*(n+2)
What is n divided by 2?
It is n/2.
What is the 34th number in this sequence 2 6 12 20?
The 34th number is 1190. First number is 2 = 2n where n = 1 Second number is 4 + 2 = 2n + 2(n-1) where n = 2 Third number is 6 + 4 + 2 = 2n + 2(n-1) + 2(n -2) where n = 3 Fourth number is 8 + 6 + 4 + 2 = 2n + 2(n-1) + 2(n-2) + 2(n-3) where n = 4 . . . In general the nth number is 2n + 2(n-1) + 2(n-2) + 2(n-3) + ..... + 2(n-n+1) and In general the nth number is 2n + 2(n-1) + 2(n-2) + 2(n-3) + ..... + 2(1) Take 2 as a common factor and we get nth number = 2(n + n -1 + n -2 + n -3 + ..... + 1) which is = 2(1 + 2 + 3 + ..... + n-3 + n-2 + n-1 + n) = 2(sum of n numbers starting with 1) But sum of n numbers starting with 1 is (n)(n+1)/2 Hence nth number in general is (2)(n)(n+1)/2 = n(n+1) Hence 34th number would be 34(34+1) = 34x35 = 1190
What is the pattern 2 4 16 3 9 81 4 16 256 5 25 625?
n, n^2, n^2^2, n+1, (n+1)^2, (n+1)^2^2, n+2, ...
Prove that 2 power n lessthan equal to n factorial lessthan equal to n power n?
Assume 2^k < k! for all n > k here n > 2, then 2^n = 2^(n - 1)*2 < (n-1)! * n = n! Done. Connie and John
What is the Answer to octagonal number sequence?

N plus 2 over n equals 110 solve for n?
(n+2)/n = 110Multiply each side by 'n':n + 2 = 110nSubtract n from each side:2 = 109nDivide each side by 109:n = 2/109
If n divided by 2 is 60 what is n?
n/2 = 60 Therefore, n = 60 x 2 n = 120
In maths what are the three consecutive even numbers that have a sum of forty two?
The numbers are 12, 14 and 16. Let the numbers by n - 2, n and n + 2, then (n - 2) + n + (n + 2) = 3n = 42 : n = 14 so n - 2 = 12 and n + 2 = 16.
