Subtract 2 from the sequence and the answer becomes obvious:
1, 4, 9, 16, 25,...,N2
Now, add the 2 back in:
3, 6, 11, 18, 27,...,(N2+2)
the rule for 3 6 11 18 27 ... is n(square)+2
Its n^ + 2n + 3
i.e... n squared + 2 + 3
1x1 + 1x2 + 3 = 6 ✓
2x2 + 2x2 + 3 = 11 ✓
3x3 + 2x3 + 3 = 18 ✓
4x4 + 2x4 + 3 = 27 ✓
5x5 + 2x5 + 3 = 38 ✓
what is the 12 term of the sequence
What will be the next number in this sequence
3,6,11,18,27,38,51. ——
2
n
3n+48
5n+3
The nth term of the sequence is (n + 1)2 + 2.
i relly dont know tony
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.
The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The 'n'th term is [ 13 + 5n ].
The nth term of the sequence is (n + 1)2 + 2.

Well, it would depend what the sequence was...? If the sequence was 2,4,6,8,10,12,14,16,18,20, then the 9th term would be 18!

24 - 6n
58
The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11
It is: 26-8n
