The rule in this case is that there are no numbers in any position.
a maths solution
They are all square numbers, and 170 isn't a square number. Very easy..
22 - 3n
once in a lower (subscript) position
4n+5
29,23,17,11
In the study of sequences, given a number n, the position to term rule tells you how the nth term of the sequence is calculated.

It is the description of a rule which describes how the terms of a sequence are defined in terms of their position in the sequence.
22 - 3n
once in a lower (subscript) position
it means the term to term use of one hundred than have to divide by three
4n+5
The nth term is 4n - 3
The nth term = 9n-2
The sum of the digits in odd position minus the sum of the digits in even position is divisible by 11.
