f = 10n + (n - 1)^2
For n=10
f = 10(10) + (10 - 1)^2
f = 181
1st term= 3 2nd term = 5 Nth term = 2n+1 10th term= 21 = 2(10)+1
The nth term is (2n - 12).
It is: nth term = -4n+14
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 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
560
The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
nth term= 6 + (n-1) (2)
It is: 26-8n
It is: 3n+1
