​

Answer 1

Answer:

$\LARGE\underline{\underline{\bf{AnsweR \: : - }}}$

let x be the first even nuber then x +2 be the second consecutive even number.

According to the question,

=> x + ( x +2) = 86

=> 2x + 2 =86

=> 2x = 84

=> x = 84 /2

=> x = 42

Hence,

• First answer = 42
• Second number x+2 = 42 +2 = 44.

Answer 2

Answer:-

• First answer = $x = 42$
• Second answer = $(x+1) = 42+2=44$

Explanation :-

Let the two consecutive even numbers be x and $(x + 2) \\ = x + (x + 2) = 86 \ <\ = x + x + 2 = 86 \\ = 2x + 2 = 86 \\ = x = 86 - 2 \\ = 2x = 84 \\ = x = \frac{84}{2} \\ = x = 42$

The largest number is $(x + 1) = 42 + 2 = 44$

• First answer = $x = 42$
• Second answer = $(x+1) =42+2=44$
