21


HENCE,

★ 5 + 8 = ?

5 + 8 × 5

5 + 40

45

Answer 2

Missing number (?) = 45

Step-by-step explanation:

We have,

1 + 4 = 5, 2 + 5 = 12, 3 + 6 = 21

To find, the value of missing number (?) = ?

The pattern follow:

(First number × Second number) + First number.

5 = (1 × 4) + 1 = 4 + 1 = 5

12 = (2 × 5) + 2 = 10 + 2 = 12

21 = (3 × 6) + 3 = 18 + 3 = 21

Similarly,

? = (5 × 8) + 5 = 40 + 5 = 45

∴ Missing number (?) = 45
