One fraction between 2/3 and 5/10 (=1/2) is (2+5)/(3+10) = 7/13
4/6/8/10
divide by 2 and add 1
The sequence appears to be increasing by 2 each time, except for the jump from 7 to 8. This suggests a pattern of adding 2, then 2, then 2, then 1. Following this pattern, the next number would be 11.
(10-2)-1 = 7 whole numbers
The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7
t(n) = 3(n-1) + 1, for n = 1, 2, 3, etc
If that's 1/4 and 2/5, 3/10 is between them.
The prime numbers between 1 and 10 are 2, 3, 5, and 7.
The prime numbers between 1 and 10 are 2, 3, 5, and 7.
21
It is: (-12+10)/2 = -1
One fraction between 2/3 and 5/10 (=1/2) is (2+5)/(3+10) = 7/13
