Answer 2

Answer:

26

Step-by-step explanation:

Average of 13 numbers = 42

Sum of those 13 numbers = 42* 13

= 546

Average of 14 numbers = 44

Sum of those 13 numbers = 44* 13

= 572

therefore,

The 14th number = sum of 14 numbers- sum of 13 numbers

= 572 -546

= 26

Hence , the 14th number is 26.
