Answer»

(1) 2 but not by 4. 

Any number which follows criteria of 4n + 2 is an example of a number divisible by 2 but not by 4. 

For example, 6 , where n= 1. 

(2) 3 but not by 6. 

Any number which follows criteria of 6n + 3 is an example of a number divisible by 3 but not by 6. 

For example, 9 , where n= 1. 

(3) 4 but not by 8. Any number which follows criteria of 8n + 4 is an example of a number divisible by 4 but not by 8. 

For example, 12 , where n= 1. 

(4) both 4 and 8 but not by 32 

Any number which follows criteria of 32n + 8 or 32n + 16 or 32n +24 is an example of a number divisible by both 4 and 8 but not by 32 For example, 40 , where n= 1.
