1.

$\huge\pink{Given:}$

sum of three consecutive odd number is 36 .

Explaination :

As we know that consecutive odd number are n , n + 2 , n + 4 .

first no. = n

second no. = n + 2

third no. = n + 4

so ,

⇒ n + n + 2 + n + 4 = 36

⇒ 3n + 6 = 36

⇒ 3n = 36 – 6

⇒ 3n = 30

⇒ $n = \frac{30}{3}$

⇒ $n = 10$

first no. = n

first no. = 10

_________________

second no. = n + 2

second no. = 10 + 2

second no. = 12

_________________

third no. = n + 4

third no. = 10 + 4

third no. = 14

2.

⇒4( 2y – 4) = 16

⇒8y – 16 = 16

⇒8y = 16 + 16

⇒8y = 32

⇒$y = \frac{32}{8}$

⇒ y = 4
