The pattern seems to involve adding consecutive numbers in a specific way.

Each row or column seems to represent a sequence of numbers, and the shaded sums may be obtained by adding certain numbers in each row or column.

+20 21 22 23 24 25 26 27 = Shaded Sum: 20 + 24 = 44

30 31 32 33 34 3 = Shaded Sum: 3

31 32 33 34 35 36 = Shaded Sum: 33 + 35 = 68

12 32 33 34 35 36 37 = Shaded Sum: 12 + 32 + 34 + 36 + 37 = 151

13 = Shaded Sum: 13

33 34 36 37 38 = Shaded Sum: 33 + 34 + 36 + 37 + 38 = 178

35 = Shaded Sum: 35

14 345 36 37 38 39 = Shaded Sum: 14 + 36 + 39 = 89

15 36 37 38 39 40 = Shaded Sum: 15 + 37 + 39 = 91

16 36 37 38 39 40 41 12-0 = Shaded Sum: 16 + 36 + 39 + 41 = 132

17 37 38 39 40 41 42 = Shaded Sum: 17 + 39 + 41 = 97

15 = Shaded Sum: 15

For example, the first row starts with +20, and each subsequent number is obtained by adding 1. The second row starts with 30, and each subsequent number is obtained by adding 1. Similarly, the first column starts with 20, and each subsequent number is obtained by adding 10. The pattern seems to involve adding consecutive numbers in a specific way.
