Question

what is the missing number in each of these sequences 5,__2
7,38

Answer 1

Step-by-step explanation:

Answer 2

Solution :-

Logic :- Given numbers are in AP with common difference as 11.

Explanation :-

→ 5 + 11 = 16

→ 16 + 11 = 27

→ 27 + 11 = 38

therefore, we can conclude that, the missing term in the series will be 16 .

Another way :-

→ First term = a = 5 ,

→ common difference = d = a4 - a3 = 38 - 27 = 11

So,

→ a(n) = a + (n - 1)d

→ a(2) = a + (2 - 1)d

→ a(2) = a + d

→ a(2) = 5 + 11

→ a(2) = 16 (Ans.)
