From the given pattern, it can be observed that,
(i) The third number is the product of the first two numbers.
(ii) The fourth number can be obtained by adding 1 to the third number.
Thus, the missing numbers in the pattern will be as follows.
42 + 52 + 202 = 212
52 + 62+ 302 = 312
62 + 70 + 422 = 432
