(10n-5)/(5)= 2n-1
just divide
10/5 = 2 and -5/5 =-1
and you get the answer
2n-1= 2n-1
Answer: 31
Step-by-step explanation:
C = 18w + 53
611 = 18w + 53
- 53 -53
558 = 18w
divide both sides by 18.
558 / 18 = 31
Out of every two consecutive numbers one will always be even. There is only one even prime number. Whether there are an infinite number of pairs of primes which differ by two (the twin prime conjecture) is still open e.g. 3 , 5; 41 , 43 ; 101 , 103 .
