Step-by-step explanation:
A prime number is a positive integer that is only divisible by 1 and itself or an integer whose factor is 1 and itself.
Example: 7
7 is divisible by 1 & 7 only
7 = 1*7 (1 & 7 are the factors of 7)
For the problem above, we have to find out what the number is before identifying if it is a prime number.
--> I'm less than 100
All the numbers from 1-99 can be considered.
--> I'm the seatmate of Mr. Half.
Mr. Half is the half of 100 which is 50.
Among 1-99 numbers, we will now choose seatmates of 50.
It could be 49 or 51.
--> I am divisible by 3 and by another odd number.
Let's find which number is divisible by 3.
49/3 = 16 Remainder 1 (not divisible by 3)
51/3 = 17 (divisible by 3)
Is 17 an odd number?
An odd number is a number that cannot be divided evenly into two groups.
17/2 = 8 Remainder 1 (17 cannot be divided evenly into two. It is an odd number)
Answer: 51, not a prime number.
