What is the 1000th triangular number?
The formula for the nth triangular number is Tn = n(n+1)/2. To find the 1000th triangular number, we substitute n = 1000 into the formula: T1000 = 1000(1000+1)/2 = 1000(1001)/2 = 500500. Therefore, the 1000th triangular number is 500500.
What are the triangular numbers 1 to 100?
0,1,3,6,10,15,21,28,36,45,55,66,78,91
What formula to find mass in a triangular prism?
Mass = Density x Volume
The formula for finding the volume of a triangular prism?
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
The 8th triangular number is 36 what is the 7th triangular number?
The formula for the nth triangular number is n(n+1)/2. If the 8th triangular number is 36, then we can set up the equation 8(8+1)/2 = 36. Solving for n, we get n = 7. Therefore, the 7th triangular number is 7(7+1)/2 = 28.
Formula of triangular numbers?
The nth triangular number is 0.5*n*(n+1)
Is 17 a triangular number?
No, 17 is not a triangular number. Triangular numbers are generated by the formula ( T_n = \frac{n(n+1)}{2} ), where ( n ) is a positive integer. The triangular numbers near 17 are 15 (for ( n = 5 )) and 21 (for ( n = 6 )), indicating that 17 does not fit into the sequence of triangular numbers.
Which numbers are both triangular and square?
The numbers that are both triangular and square are known as "triangular square numbers." The first few of these numbers are 1, 36, and 1225. They can be generated by solving the equation ( n(n + 1)/2 = m^2 ) for positive integers ( n ) and ( m ). The general formula for finding these numbers involves using the Pell's equation related to the sequence of triangular numbers.

What triangular numbers are greater than 20?
Triangular numbers are generated by the formula ( T_n = \frac{n(n+1)}{2} ). The triangular numbers greater than 20 are 21, 28, 36, 45, and so on. Specifically, the first few triangular numbers greater than 20 are ( T_6 = 21 ), ( T_7 = 28 ), ( T_8 = 36 ), and ( T_9 = 45 ).
Is the number 100 a triangular number?
No, the number 100 is not a triangular number. Triangular numbers are formed by the formula ( T_n = \frac{n(n + 1)}{2} ), where ( n ) is a positive integer. The closest triangular numbers to 100 are 91 (for ( n = 13 )) and 105 (for ( n = 14 )). Since 100 does not match any triangular number in this sequence, it is not triangular.
What are the next triangular njmbers after 15?
The next triangular numbers after 15 are 21, 28, and 36. Triangular numbers are formed by the formula ( n(n+1)/2 ), where ( n ) is a positive integer. For ( n = 6 ), the triangular number is 21; for ( n = 7 ), it is 28; and for ( n = 8 ), it is 36.
What numbers are their in a triangular numbers?
None. There is nobody to whom triangular numbers belong.
What is the triangular number of 30?
Triangular numbers can be calculated by using the following formula (n * (n+1) ) / 2 so for 30 the answer is (30*31)/2 = 465
What are the first 5 triangular numbers?
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.
What two triangular numbers make sixteen?
6 and 10 are triangular numbers that make 16.
