Write seven consecutive composite numbers less than 100 so that there is no prime number between them.

Answer :

Between 89 and 97, both of which are prime numbers, there are 7 composite numbers,


90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90


91 = 1, 7, 13, and 91


92 = 1, 2, 4, 23, 46, and 92


93 = 1, 3, 31 and 93


94 = 1, 2, 47, and 94


95 = 1, 5, 19 and 95


96 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48 and 96

Hence, 90,91,92,93,94,95 and 96 are the composite numbers between 89 and 97.
