Answer:
Let’s look at the first equation;
7 + 3 = 410
The result is actually of the form
(a + b) = (a – b),(a+b)
So (7-3)(7+3) =410;
Similarly this equation will fit in all the following sequences.
So to find ? we substitute the numbers in our equation; 5 + 4 = ?
i.e (5-4)(5+4) = 19.
Hence 5 + 4 = 19
