There's this question that was the subject of controversy in a thread i follow. It goes thus:

On a certain day, a teacher said, 'If yesterday was tomorrow, today would have been Friday.'
What day is today?

I'd really appreciate it if you all commented on this.

bukatyne:

I am getting 83/91
The answer is actually 91. How?
2+3=5,5*3=15
3+4=7,7*4=28
4+5=9,9*5=45
5+6=11,11*6=66
6+7=13,13*7=91
OR
Difference between 15 & 28=13
;28 & 45=17
;45 & 66=21
13,17,21 indicates differences of 4
There4;The nxt number shud b 25
Now 25+66=91.

I did the second method and got 91

I also did something else..

I subtracted the 4th column from the 3rd:

15 - 12 = 3
28 - 20 = 8
45 - 30 = 15
66 - 42 = 24

3 8 15 24 ? i.e. difference between the two differences
5 7 9

we can see the difference is 2 therefore, the next will be 11 1.e. 11 + 24 = 39

39 + 56 = 95

It should be 95 and not 84
