The pattern in the given groups is that the middle number is the sum of the first and last numbers plus 7.

In the first group, 19 + 18 = 37, and 37 + 7 = 44, but the middle number is 30, which is 14 less than 44.

In the second group, 8 + 17 = 25, and 25 + 7 = 32, but the middle number is 18, which is 14 less than 32.

So, in the third group, 13 + 4 = 17, and 17 + 7 = 24. But we need to subtract 14 from this sum (as per the pattern), so 24 - 14 = 10.

Therefore, the number that completes the last group is 10.

Therefore, the number that completes the last group is 10.

The three numbers in each group are related in the same way.Choose the number that completes the last group.( 19 [ 30 ] 18 )( 8 [ 18 ] 17 )( 13 [ ? ] 4 )
