5-2n=3 -2n=3-5 -2n=-2 n=1
Nonsense.
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
n = 1
On = 2n - 1 so O13 = 2*13 - 1 = 26 - 1 = 25
1/2
If: 2n = 1 Then: n = 1/2 or 0.5
1
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
1 + 2 + 4 + ... + 2n = 2n+1 - 1
5-2n=3 -2n=3-5 -2n=-2 n=1
2n+2n equals 4n
Nonsense.
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
2n plus 7 equals 19 2n equals 12 n equals 6
the answer is 0
