What is the value of
5+x=?
Answers
Step-by-step explanation:
As with almost all math questions, I went to Excel, because I are a dullard.
A1 = seed number (started with 1)
A2 thru A30 = {cell above} +1
B1 = 5*A1
C1 = 5+A1
D1 = B1/C1
Copied B1 thru D1 to B2 thru B30
initially A1 was 1
D1 = .833333, D5 = 2.5, D15 = 3.75, D20 = 4
A30 = 30, B30 = 150, C30 = 35, and D30 = 4.285714
Set A1 = 31
A30 = 60, B30 = 300, C30 = 65, D30 = 4.615385
Long Story Short . . .
Set A1 = 1000000
A30 = 1000029, B30 = 5ooo145, C30 = 1000034, D30 = 4.999975
From that point on, the D-column numbers continue to increase, approaching 5, but never quite reaching 5.
Set A2 thru A30 = {cell above} -1
Set A1=0. D1=0
Experimented with increments <1 and discovered the following:
If x=-2.5, the equation calculates to -5. If dealing with absolute values, we’d have our answer.
For x=-1 thru -4, the respective results are -1.25, -3.333333, -7.5, and -20.
x=-5 results in a DIVISION BY 0 error.
For x=-6 thru -10, the respective results are 30, 17.5, 13.333333, 11.25, and 10.
From that point on, the D-column numbers continue to decrease, approaching 5, but never quite reaching 5.
According to my Excel spreadsheet, there is no answer.
