3+4= 7 7+4=11 11+4= 15 15+4=19 19+4=23 23+4=27 27+4=31
its Mersenne's Number f(n)= (2^n) -1 where n is the number of sequence. so f(1) = 1 f(2) = 3 f(3) = 7 f(4) = 15 f(5) = 31 ...
39
It is: 4 and 3/7 as a mixed number

31 because 3+4=7+4=11+4=15+4 does not equal 31
3+4= 7 7+4=11 11+4= 15 15+4=19 19+4=23 23+4=27 27+4=31
its Mersenne's Number f(n)= (2^n) -1 where n is the number of sequence. so f(1) = 1 f(2) = 3 f(3) = 7 f(4) = 15 f(5) = 31 ...
47
They are: 2, 17, 3, 7 and 31
7
It is 43 because 31+12 = 43
