What is the nth term of 6 15 28 45 66?

Answer 1

Oh, what a lovely sequence you have there! To find the pattern, let's look at the differences between the numbers: 9, 13, 17, 21. Do you see how the differences are increasing by 4 each time? That means the nth term is found by adding the square of n to the previous term. Happy math-ing, my friend!

Answer 2

To find the nth term of a sequence, we first need to identify the pattern. In this case, the differences between consecutive terms are 9, 13, 17, and 21. These differences do not form a simple arithmetic progression, so the sequence likely involves a quadratic equation. By analyzing the pattern further, we can determine the general formula for the nth term.

Answer 3

6 = 2 * 3

15 = 3 * 5

28 = 4 * 7

45 = 5 * 9

66 = 6 * 11

Assuming the pattern continues, the nth term is (n + 1) * (2n +1) = 2n^2 + 3n + 1.
