In this question we need to check every option available to us and as soon as we get the right answer we will choose that option . the given sequence is 2 * 4 * 3 * 4 * 9 option A) + × = - 2 + 4 x 3 = 4 - 9 here , 14 =/= -5 , So option A is not valid
option B) × - + = 2 x 4 - 3 + 4 = 9 , Using BODMAS,
8 - 3 + 4 = 5 + 4 = 9 here we see that 2nd option is satisfying the given equation , hence our answer is option B
