Question

The average of four consecutive odd number is 28. Find the largest number ?​

Answer 1

Answer :

• Largest number is 31

Given :

• The average of four consecutive odd number is 28

To find :

• Largest number

Solution :

• Let the numbers be x , x + 2 , x + 4 , x + 6

Given that,

• Average of four consecutive odd number is 28

》x + x + 2 + x + 4 + x + 6 / 28

》4x + 12 = 28 × 4

》4x + 12 = 112

》4x = 112 - 12

》4x = 100

》x = 100/4

》 x = 25

Hence ,

• x = 25
• x + 2 = 25 + 2 = 27
• x + 4 = 25 + 4 = 29
• x + 6 = 25 + 6 = 31

Therefore , Largest number is 31

Answer 2

$\sf \: Let \: the \: no. \: be \: x, \: x+1, \: x-1$

$\frac{x + x + 1 + x - 1}{3} = 28 \\ 28 \times 3 = 3x \\ \boxed {x = 28}$

$\sf \: Largest \: no. \rightarrow \boxed{ \boxed{x + 1 = 29}}$
