Question

5+9=28
3+16=12
2+38=10
6+9=?​

Answer 1

Answer:

38

Step-by-step explanation:

5+9=28, 3+16=12, 2+36=10, 6+9=

5 + 9 = 28

=> 5² + √9 = 28

=> 25 + 3 = 28

3+16=12

=> 3² + √16  - 1= 12

=> 9 + 4 - 1= 12

=> 12 = 12

2+36=10

=> 2² + √36 = 10

=> 4 + 6 = 10

=> 10 = 10

6+9= ?

=> 6² + √9  - 1 = ?

=> 36 + 3 - 1 = ?

=> 38 = ?

Rule here is

a + b = c

=> c = a²  + √b     for odd sequence numbers

& c = a²  + √b - 1  for even sequence numbers
