Answer 1

Answer : $\bold{5,5 \: = \: 1025}$



Explanation -


Given :

1,1=21 2,2=44 3,3=69 4,4=816 5,5=?


First, Add the same number then Multiply with same number -


1 + 1 , 1 x 1 = 21

2 + 2 , 2 x 2 = 44

3 + 3 , 3 x 3 = 69

4 + 4 , 4 x 4 = 816

5 + 5 , 5 x 5 = 1025


Hence :


$\bold{Answer : 5,5 \: = \: 1025}$

Answer 2

Answer:

1025

Step-by-step explanation:

here we need to observe the given pattern of numbers. First numbers are addition and the second numbers are square of the numbers. So the sequence is as follows:

1 + 1 , 1 x 1 = 21

2 + 2 , 2 x 2 = 44

3 + 3 , 3 x 3 = 69  

4 + 4 , 4 x 4 = 816  

5 + 5 , 5 x 5 = 1025

Finally we get the answer as 1025.
