the answer is of course 12
What is the difference between rational and irrational in math?
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
What are the trianglular numbers between 1 and 200?
The triangular numbers between 1 and 200 are 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120, 136, 153, 171, and 190. They are quite simple to find--each triangular number is one more than the difference between the previous two triangular numbers. For example, the difference between 55 and 66 is 11, so the next higher triangular number will be 78, 12 more than 66.
what is rational or irrational numbers?
The difference is that rational numbers can be expressed as fractions whereas irrational numbers can not be expressed as fractions.
Difference between rational and irrational?
Rational numbers can be expressed in the form p/q (where q is not equal to zero). Irrational numbers cannot be expressed in this form. For example, the square root of 2 cannot be expressed as p/q.
What is the difference between 35 and 98 expressed as a decimal?
Depending on what you mean, it could be 63.0 (if the numbers are 35 & 98), or 0.63 (if the numbers are 0.35 & 0.98).

Smaller of two triangular numbers whose sum and difference are also triangular numbers?
The answer would be 15 and 21. The triangular numbers are 1,3,6,10,15,21,28,36,45,55,66,78. 15 plus 21 is 36 which is on the list. 21 minus 15 is 6 and that is on the list as well.
What are the triangular numbers between 1 and 66?
The triangular numbers between 1 and 66 are: 3, 6, 10, 15, 21, 28, 36, 45 and 55.
What triangular numbers are between 40 and 50?
Only 45.
How many triangular numbers are there between 100 and 200?
Six.
What is the difference between an irrational number and a rational numbers?
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
