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

Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...

x2-3=n

The nth term is 22n and so the next number will be 5*22 = 110

It is: nth term = 29-7n

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,...)

If you meant: 2 12 22 32 then the nth term = 10n-8

The nth term is 5n-3 and so the next term will be 22

3n+1

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 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 of an arithmetic sequence is given by. an = a + (n – 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.

The simplest rule for the given numbers is the fourth order polynomial: Un = (n4 - 10n3 + 35n2 - 266n + 768)/24 for n = 1, 2, 3,

You must mean what is the next number in the series, not the 'nth', which is undefined. The next number is 58.
