If
1,4,3=13;
4,5,4=9;
5,6,5=11 and
7,7,6=7
then
9,8,7=?

posted Jul 27, 2017

1,4,3=13
4-1=3
3×3=9
9+4=13
like this
8-9=-1
-1x7=-7
-7+8=1

Hopefully this will help someone.
1,4,3=13
4-1=3
3×3=9
9+4=13

I actually wanted others to use the formula and solve it themselves. Just follow the formula and you will get it
Ans is 1

1,4,3 - 1st number, 2nd number and 3rd number

(2nd number - 1st number) x 3rd number + 2nd number

(4 - 1) x 3 + 4 = 13
(5 - 4) x 4 + 5 = 9
(6 - 5) x 5 + 6 = 11
(7 - 7) x 6 + 7 = 7
(8 - 9) x 7 + 8 =1

wrong!!!!

Can also be solved as A, B, C

B squared - (A * C)

in my puzzle the previous responses would have resulted in 16 as the answer, but the correct answer was 79 and can only be derived using B Sqaured - (A*C)
1,4,3=13
4,5,4=9
5,6,5=11
7,7,6=7
2,9,1 =?

(4×4) - 1 × 3 = 13
(5×5) -4 × 4 = 9
(6×6) - 5 × 5 = 11
7 × 7 - 7 × 6 = 7
8 × 8 - 9 × 7 = 1ans
So right ans is 1

If the following is true, can you find the value of (4 + 9)?

7 + 7 = 2
8 + 8 = 4
8 + 5 = 1
6 + 9 = 3
10 + 11 = 9

IF
1,3,3=5
9,7,4=8
11,14,10=15
20,16,12=18
Than
3,6,7=?
