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.
The given sequence appears to follow a pattern. Let's analyze the differences between consecutive terms:
8 - 2 = 6
16 - 8 = 8
26 - 16 = 10
38 - 26 = 12
52 - 38 = 14
The differences between consecutive terms are increasing by 2 each time. So, to find the next term in the sequence, add 16 (the previous difference) and 2:
14 + 2 = 1614+2=16
Now, add this difference to the last term in the sequence:
52 + 16 = 6852+16=68
Therefore, the next term in the sequence is 68.
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
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
Sn = -8n + 2S0 = -8(0) + 2 = 2S1 = -8(1) + 2 = -6S2 = -8(2) + 2 = -14S3 = -8(3) + 2 = -22S4 = -8(4) + 2 = -30S5 = -8(5) + 2 = -38
It depends on the speed you are going.
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
2 + ((6 + 2 * (n - 1) * (n - 1))
[ 6n + 8 ] is.
Each number is increasing by increments of 8 10 12 14 ... etc and so the next number will be 52+16 = 68
It depends what the next number in the sequence is. The simplest polynomial for those 5 terms is: U{n} = n² + 3n - 2
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
The nth term of the sequence is (n + 1)2 + 2.
9n+2
The 'n'th term is [ 13 + 5n ].
The 'n'th term is [ 13 + 5n ].
The 'n'th term is [ 13 + 5n ].
58
If the term number is n, then the nth term is 10(n-1) +8.
