Add 4 each time
It's every other odd number.
The rule for the pattern is y=x+2. That rule is in the table format in which it would originally be in, but the worded rule would be 'It increases by 2 each time'.

+5
Add 4 to the previous number
The 13 should be 31... then 1+1+1=3 1+1+3=5 1+3+5=9...
The rule of this pattern is obfuscated by the omission of spaces, giving the impression that this is the number "111,359,173,157". However, the underlying pattern follows the function of the Fibonacci series, but adding sets of 3 instead of sets of 2. So, 1+1+1=3, 1+1+3=5, 1+3+5=9, 3+5+9=17, 5+9+17=31, 9+17+31=57.
add 4 to every other number 1(+4)=5, 5(+4)=9 2(+4)=6
+2, probably.

consecutive square numbers
1/5 > 1/9 To test Bring both fractions to a common denominator of 45' Hence 9/45 & 5/45 Compare numerators 9 > 5 Hence it follows 9/45 > 5/45 1/5 > 1/9 NB As a rule of thumb , the larger the denominator , then the smaller the fraction.
+5
-9
The pattern rule is: 4 5 6 7 8 and so the next number will be 33+9 = 42
Add 4 to the previous number
Oh, dude, it's like the pattern rule here is just adding 9, then multiplying by 3. So, you go from 5 to 14 by adding 9, then from 14 to 41 by multiplying by 3 and adding 5, and so on. But hey, who needs patterns when you have Netflix, am I right?
The simplest is Un = 2n + 1
