There are 94 of them so I guess you will have to work them out - best to use the sieve method.
The greatest composite number between 17 and 140 is 138. A composite number is defined as a positive integer that has at least one positive divisor other than one and itself. Since 138 can be factored into 2 and 69, it meets the criteria of a composite number.
289 is composite. 289 = 17 * 17 = 172
The number after 17 is 18.
15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
17 is not a composite number, it is a prime number because it has only two factors itself and one. A composite number has more than two factors.

17 is a prime number - the next composite number after 17 is 18.
289 is composite. 289 = 17 * 17 = 172
The number after 17 is 18.
17 is not a composite number because composite numbers have other factors aside from 1 and itself. Factors of 17 are only 1 and 17, thus, 17 is a prime number.
15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
No
Composite: 17 * 137
17 is not a composite number, it is a prime number because it has only two factors itself and one. A composite number has more than two factors.
No.
697 is not prime. 697 = 17 * 41
17 is prime.
