• Answer is 9br /Reason: It is a series following -1 ,+1 patternbr /Approching this question from the second  last no of the series will make it easier to solvebr /1.37*2= 74+1= 75br /2.19*2=38-1=37br /So the next no of the series should be (x)*2+1=19 which gives x=9br /and going back to the first no 5*2-1=9 which justifies the required no. br /Hence the answer is 9.br /
