  • answer is 9br /br /75 previous number is 37 so 37*2+1=75br /37 previous number is 19 so,19*2-1=37br /      assume 19 previous number is x:br / 19 previousnumber is x so x*2+1    br /by substitute the given options in xbr /                      1.10*2+1=21(is not the next number)br /                      2.9*2+1==19(is the next number)br /                     3.3*2+1=7br /                     4.8*2+1=17br /so the option 2 is correct bcz  x of next number is 19br / 


  • 9 because in this series the order is that even term is double of first term plus 1 and odd term is double of second term minus 1 so following this series we get the unknown no by 2×2+1=5 5×2-1=9 9×2+1=19 so the answer is 9.
