Answer:
Explanation 1:
1+4 = 4x1 + 1 = 5
2+5 = 5x2 + 2 = 12
3+6 = 6x3 + 3 =21
The logic here is : Multiply the two digits on left-side and to this product add the first number on the LHS. This gives the number on right-side. Applying this logic to the next two, we write
4+7 = 7x4 + 4 = 28 + 4 = 32
5+8 = 8x5 + 5 = 40 + 5 = 45 (Proved)
Explanation 2:
Given:
1+4 = 5
2+5 = 12
3+6 = 21
If you take differences of numbers on right,
12–5 = 7
21-12 = 9.
This shows that the differences between successive numbers on right-side are in A.P. with common difference = 2. Following this pattern, the next difference will be 11 and consequently the next number on right-side will be 21+11 = 32 and
4+7 = 32.
The next number on right-side will be 32+13 = 45 and
5+8 = 45 (Proved)
