Question

Plz answers and I have your humbal request to not writ anything stupid.
Thankyou

Answer 1

23 and 29 so (29-23)=6

Answer 2

Let S be the set of numbers between 20 and 30.

S=21,22,23,24,25,26,27,28,29

Excluding all numbers where  $\frac{m}{2}$∈R . Therefore,

S = {21, 23, 25, 27, 29}.

Further exclude 21, 25, and 27 as they are divisible by 3, 5, and 3 respectively.

That is,

The set of primes  S  = {23, 29}.

Hence,

29 - 23 = 6 or 23 -29 = -6
