If the nth term is n*7 then the first 5 terms are 7, 14, 21, 28, 35.
The nth term is (36 - 4n)
t(n) = n2 + n + 8
The nth term of the sequence is expressed by the formula 8n - 4.
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, ...
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

28
nth term is n squared plus three
If you mean: 8 28 48 and 68 then the nth term is 20n -12 and so the next number will be 88
28 - 8n
