2+5=10
6+4=43
7+2=56
9+9=?

Answer 1

Answer:

97 is your answer

Step-by-step explanation:

square of 2 + 5 (+1) = 10

square of 6 + 4 (+3) = 43

square of 7 + 2 (+5) = 56

square of 9 + 9 (+7) = 97

Answer 2

2 + 5 = 10

6 + 4 = 43

7 + 2 = 56

9 + 9 = 97

Solution:

2 + 5 = 10

6 + 4 = 43

7 + 2 = 56

9 + 9 = ?

Analyse the given pattern and find out the logic

$2+5 = 2^2 + 5 + 1 = 4 + 5 + 1 = 10\\\\6 + 4 = 6^2 + 4 + 3 =36 + 4 + 3 = 43\\ \\7 + 2 = 7^2 + 2 + 5 = 49 + 2 + 5 = 56 \\\\9 + 9 = 9^2 + 9 + 7 = 81 + 9 + 7 = 97$

Thus the pattern followed is:

$a + b = a^2 + b + (2n - 1)$

Where, n = 1 , 2 and so on

Thus the missing term is 97
