Question

Triangle missing number:
5 3 4 =18
3 5 3 =65
9 6 3 = ?

Answer 1

Given:-

5,4,3=18 , 3,5,3=65

•Solution:-

According to the first format

5²- (3+4) - 0

= 25 - 7 = 18

And the second series is

3⁴ - (5×3) -1

=81 - 15 - 1

= 65

So the format is like

A²- (B+C) - 0

then A⁴ - (B×C) - 1

for the third series we have to alter the equation on like

A²- (B+C) - 2

so, 9² - (6+3) - 2 = 81-9-2= 70

So the final answer is 5,4,3=18 , 3,5,3=65 , 9,6,3=70

Answer 2

9 6 3 = 72

Step-by-step explanation:

The pattern followed in the given series is:

A²- (B + C) - n

A⁴ - (B × C) - n

Where,

n = Whole numbers = 0, 1, 2, .....

5 3 4 = 18

⇒ 5² - (3 + 4) - 0

⇒ 25 - 7 = 18

3 5 3 = 65

⇒ 3⁴ - (5 × 3) - 1

⇒ 81 - 15 - 1 = 65

9 6 3 = ?

⇒ 9² - (6 + 3)

⇒ 81 - 9 = 72
