The nth term for the triangular numbers can be expressed using the formula ( T_n = \frac{n(n + 1)}{2} ), where ( n ) is a positive integer representing the position in the sequence. This formula calculates the sum of the first ( n ) natural numbers, resulting in the sequence 1, 3, 6, 10, 15, 21, and so on. For example, for ( n = 4 ), ( T_4 = \frac{4(4 + 1)}{2} = 10 ).

What is the nth term of 1 3 6 10 15 21?
The sequence 1, 3, 6, 10, 15, 21 consists of triangular numbers, where the nth term can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). This formula represents the sum of the first n natural numbers. For example, for n = 1, the term is 1; for n = 2, it is 3, and so on. Thus, the nth term is the sum of the integers from 1 to n.

Numbers 1 3 6 10 15 pascals triangle?
Well...the fifth row is 1 5 10 10 5 1...but to possibley solve a problem you need a formula for example (x+y)^2 * * * * * No, these are triangular numbers. The formula for the nth term is t(n) = n(n+1)/2 They are called triangular numbers because if you make one mark on the first line, two marks on the second, three on the third, etc you will generate these numbers and with each line the marks form a triangular shape.

What is the nth term for 10 6 2 -2?
It is: nth term = -4n+14
What is the nth term of -10 -8 -6 -4 -2?
The nth term is (2n - 12).
How do you find the nth term?
Say if you had the pattern 15 20 25 30 35 40 45 50 To find the nth term you have to see what the gap between the numbers is. In our case this is 5. Then you have to find out what the difference between the gap and the first number. In this sequence it is 10. So your answer would be..... 5n+10 That's how you find the nth term.
What is the nth term of -8 2 12 22?
The sequence has a difference of 10, so the nth term starts with 10n. Then to get to -8 from 10 you need to subtract 18. So the nth term is 10n - 18.
