5=22+12 8=22+22 13=22+32 20=22+42 29=22+52 40=22+62
The nth term is 3n+7 and so the next number will be 22
3n+7
The first differences are 5, 7, 9, 11, 13 and the second differences are 2,2,2,2 so the formula for the nth term is a quadratic. tn = n2 + 2n - 2 (n = 1,2,3,...)
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.
5=22+12 8=22+22 13=22+32 20=22+42 29=22+52 40=22+62
The nth term is 3n+7 and so the next number will be 22
x2-3=n
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
3n+7
If you meant: 2 12 22 32 then the nth term = 10n-8
It is: nth term = 29-7n
The nth term is 5n-3 and so the next term will be 22
The first differences are 5, 7, 9, 11, 13 and the second differences are 2,2,2,2 so the formula for the nth term is a quadratic. tn = n2 + 2n - 2 (n = 1,2,3,...)
the nth term is = 31 + (n x -9) where n = 1,2,3,4,5 ......... so the 1st term is 31+ (1x -9) = 31 - 9 =22 so the 6th tern is 31 + (6 x -9) = -23 Hope this helps
The nth term is -7n+29 and so the next term will be -6
The nth term is 22n and so the next number will be 5*22 = 110
