22, and 21, and 33. 22 x 21 x 33, as a single entity is a measure of volume and cannot be converted to a linear measure.
Because of the pattern of plus 11 then minus ten I would go with 13 24 14
Well, start with any decimals u have, like 0.36. that is first. then the single digits, like 1, which is next. then 13, 23 and finally 33. since 13 is lower then 23, which is lower then 33. so the order is 0.36, 1, 13, 23, 33.
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 'n'th term is [ 13 + 5n ].
The 'n'th term is [ 13 + 5n ].
It is: 10n-7 and so the next term is 43
The 'n'th term is [ 13 + 5n ].

18,23,28,33,... #1 is 18 #2 is 23 A difference of '5' Hence we can write '5n + x = 18 Where 'n' equals '1' Hence 5(1) + x = 18 5 + x = 18 Hence x = 18 - 5 = 13 So nth term is 5n + 13 NB Verification; does it work for the 4th term 5(4)+ 13 = 20 + 13 = 33 Which is true from above list.

It is increasing by 4 and the nth term is 4n+1
Here are the first five terms of a sequence. 12 19 26 33 40 Find an expression for the nth term of this sequence.
All you have to do is add 5 each time(x+5) It's 43
6+13+22+33 = 74
