It is 5n-4 and so the next term will be 21
10n + 1
nth term = 5 +8n
t(n) = n2 + 5n - 3
tn = 2x2 + 3 where x = 1, 2, 3, ...
It is 5n-4 and so the next term will be 21
10n + 1
81
nth term = 5 +8n
t(n) = n2 + 5n - 3
The nth term is 25-4n and so the next term will be 5
It is 4n+5 and so the next term will be 25
tn = 2x2 + 3 where x = 1, 2, 3, ...
Clearly here the nth term isn't n25.
The problem is finding the next term 7 9 13 21 37 69 133 261......... nth the first number aka the N1 = 7, N2 = 9, N3= 13,....... N7= 133,........Nth The first number 7 +2 = 9, which is the second number NOTE: 21=2 the second number 9 + 4 = 13 NOTE: 22=4 the third 13 + 8 = 21 NOTE: 23=8 the fourth 21 +16 = 37 NOTE: 24=16 So, the pattern is Nm+2m= the next number in the pattern Nth = Nth-1+2th-1 By: Rodney T.

The given sequence (7, 14, 21, 28, 35,....) is an arithmetic sequence where each term increases by 7. The nth term of the given sequence is 7n
