It is: -6n+22
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.
The Nth term in the series is [ 2N ] .
The nth term is equal to 4n.
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

Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
4 10 16 22 28 34 40 ....... Each term is increased by 6 or nth term = 6n-2
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.
