first three prime nmbers are 5,7,11 last three are 13,11,7
There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .
There is no last prime number: they go on for ever. The first prime larger than 100 is 101.
There cannot be the last two prime numbers because there are an infinite number of them.
194.
the answer is 13 the 4 prime numbers are 5,7,11,13 product of first three is 5*7*11=385 and,that of the last three is 7*11*13=1001,so the largest given prime is 13

The last prime number from 1 to 100 is 97, and the first is 2. 97+2 = 99
There cannot be the last two prime numbers because there are an infinite number of them.
31 + 59 = 90
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
It is 0.
The last two prime numbers before 30 are 29 and 23.
