None. There is nobody to whom triangular numbers belong.
It is necessary to know which of three of the four given numbers are the sides of the triangular cross section and which one in the length. Without that information it is not possible to answer the question.It is necessary to know which of three of the four given numbers are the sides of the triangular cross section and which one in the length.

The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.
Nope Triangular numbers are 1,3,6,10,15,21,28,36

Triangle numbers or triangular numbers are those numbers that can form an equilateral triangle when counting the objects. The first five triangular numbers are: 1, 3, 6, 10, 15.
the next three numbers are 180 540 and 1620=)
It can be hard to answer questions of this type based on only three examples. However, that does happen to be the start of the sequence called the "triangular numbers" ... that is, those quantities that can be arranged in an equilateral triangle (like bowling pins or billiard balls). The next number in the triangular sequence is 10 (followed by 15, 21, 28, etc).
6 and 10 are triangular numbers that make 16.
The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.
Nope Triangular numbers are 1,3,6,10,15,21,28,36
1,36,1225,41616,1413721
the answer is of course 12
