Answer 1

Please explain your question properly.

Answer 2

Answer:

66

Step-by-step explanation:

You will have to take double difference.

14-11=3,19-14=5,28-19=9 , 43-28=15

Now taking the difference between the newly obtained numbers you'll find that they are the even numbers.

5-3 = 2 , 9-5=4 , 15-9=6, so the next number must be 8.

Now perform the double addition

Therefore, 15+8=23

23+43 = 66
