nth term = n*(n+2)+(n-2) when
1st term = 2; 2nd term = 8; 3rd term = 16; 4th term = 26; 5th term = 38; 6th term = 52
Step 1: look at n=3 and 4 and try to come up with a formula that is close
Step 2: first try multiplication for n=3 which should be 16 which is close to 3x5; for n=4 it should be 26 which is close to 4x6
Step 3: so the first part that works is n(n+2) but this only gets us close, not exact
Step4: for n=3 which is 16 is n(n+2)+1; for n=4 it is 26 which is n(n+2)+2
Step 5: so now we can try n(n+2)+(n-2). We test this for n=5 which is 38. 5(5+2)+(5-25) = 38. Test again for n=6 which is 52. 6(6+2)+(6-2) = 52...so all good.

What is the nth term for the sequence 10 17 24 31 38?

What is the nth term rule of 11 20 29 38 47?
There are infinitely many possible answers. Given ANY number, it is always possible to find a polynomial of order 5 [at most] that can be used as the nth term rule for the given five number and the additional sixth. There are also non-polynomial solutions. Each different sixth number will result in a different polynomial and, since there are infinitely many sixth numbers, there are infinitely many answers to the question. Having said that, the simplest polynomial solution is Un = 9n - 2

How many different possible license plates are there?
Given that the effective limit on the number characters on a license plate is 7, and that each of those characters could be a letter (26 possibilities), a number (10 more possibilities, 36 total), a hyphen (37 total), or a space (38 total possibilities), the total number of possible license plates is 38^7 or 38*38*38*38*38*38*38 which is 114,415,582,592

What is the nth term of 3 6 11 18 27?
The given sequence is an arithmetic sequence with a common difference that increases by 1 with each term. To find the nth term of an arithmetic sequence, you can use the formula: nth term = a + (n-1)d, where a is the first term, n is the term number, and d is the common difference. In this case, the first term (a) is 3 and the common difference (d) is increasing by 1, so the nth term would be 3 + (n-1)(n-1) = n^2 + 2.
