70 and 90
2-69
51,52,54,55,56,57,58,60,62,63,64,65,66,68,69 are the composite numbers between 50 and 70.
ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.

ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.
Composite numbers are positive integers greater than 1 that have more than two factors. Between 61 and 71, the composite numbers are 62, 63, 64, 65, 66, 68, 69, and 70. These numbers can be divided evenly by numbers other than 1 and themselves, making them composite.
For instance, all the even numbers greater than 70 are composite.The next few composite numbers greater than 70 are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, ...
