The nth term is equal to 4n.
Un = 29 - 9n
tn = 34 - 9n where n = 1,2,3,...
The Nth term in the series is [ 2N ] .
Clearly, if you omit the sign, the nth. term will be 4n. The alternating sign can easily be expressed as a power of (-1), so in summary, the nth. term is (-1)n4n.
It is 5n-4 and so the next term will be 21
5n+1
The nth term is equal to 4n.
Un = 29 - 9n
tn = 34 - 9n where n = 1,2,3,...
The Nth term in the series is [ 2N ] .
The nth term is 9n-2
The nth term is 3n+7 and so the next number will be 22
The nth term is: 3n+1 and so the next number will be 16
We note the sequence goes up in steps of '8' Hence '8n'. Next for step #1 4#1 ; n = 1 ; 8(1) + c = 16 8 + c = 16 c = 8 Hence the nth terms is 8n + 8 Verifications When n = 3 ; 8(3) + 8 = 24 + 8 = 32 ( which is true).
(n2+n+2) / 2, starting with n=0.
The nth term is 22n and so the next number will be 5*22 = 110
