13211321322112 This line describes the last line. Each two digits describes how often a number repeats. One three, two one's, one three, two one's, three two's, three two's, two one's, one two. The problem with the sequence provided is the fourth set where there has been a typo (31112) should be (3112).
It's the look-say sequence starting with 2. initially, starting with 2, you see that there is one 2, hence 12. looking at this, you see there is one 1 and one 2, giving you 1112, and so on.
1 / 1112 the reciprocal of any number is just 1 divided by that number, e.g the reciprocal of 4 is a quarter, of 2 is a half etc.
The next number is 1112.

This is a "Look and Say" sequence; you get the next term by looking at the previous one and saying what digits it contains. 2 contains "one 2", so the second term is 12; that is then "one 1, one 2", yielding 1112, and so on.
It is already a whole number as 1112
1112 is a rational number
710 = 1112
1 / 1112 the reciprocal of any number is just 1 divided by that number, e.g the reciprocal of 4 is a quarter, of 2 is a half etc.
An even number is exactly divisible by an even number, 1112 divided by 2 is 556
111 222 1112
1112/1
1112 which, in decimal, is 7
The next number is 1112.
