Step-by-step explanation: Here if you see carefully, the first number is 2. If you multiply 2 by 2 you will get 4. Now add one to it, you will get 5. The second number is five. Again you are multipling by it 2. Now INSTEAD of adding, subtract 1 from it. You will get 9. The third number is 9. Again you have to multiply it by 2 and again you have to add 1 to it . So the result will be 19. The fourth number is 19 and again you have to multiply it by 2 and subtract 1 from the result. The result will be 37. So, the sequence is that, first you multiply the number by 2 and add 1 in the first case, subtract 1 in the second case and this cycle repeats. So the sixth number will be 75(37*2+1). Hope it helps you. |
