13/2+7/2=1+3*13/2-2
Answers
Answer: METHOD 1 :
(A,B = C) , (smaller no.)^2 + (other number)= C
(1,1 =2) , 1×1 + 1 = 2
(2,3 =7) , 2×2 + 3 = 7
(3,4 =13) , 3×3 + 4 = 13
(5,6 =31) , 5×5 + 6 = 31
(12,11 =133) , 11×11 + 12 = 133
If we consider A×A + B = C for this method then the answer will be 155, this can also be correct as all other triplets follow this formula as in those triplets the first two numbers are in ascending order, which is not the case for the asked triplet.
This is why there can be these 2 possible answers for this square and add method.
METHOD 2
(A,B = C) , A×B + 1 = C
(1,1 =2) , 1×1 + 1 = 2
(2,3 =7) , 2×3 + 1 = 7
(3,4 =13) , 3×4 + 1 = 13
(5,6 =31) , 5×6 + 1 = 31
(12,11 =133) , 12×11 + 1 = 133
