\boxed{\boxed{\bf{Given:}}}

The sum of five consecutive odd natural number is 165​.

\boxed{\boxed{\bf{To\:\:be\:\:found:}}}

All the five consecutive odd natural numbers whose sum is 165​.

Let one odd number be \red{\sf{x}}.

other odd consecutive numbers will be

\red{\sf{x+2}}, \red{\sf{x+4}}, \red{\sf{x+6}}, \red{\sf{x+8}}

\red{\underline{\tt{According\:\:to\:\;the\:\:question-}}}

x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 165

→ 5x + 20 = 165

→ 5x = 165 - 20

→ 5x = 145

→ x = 145 ÷ 5

→ x = 29

So,

The first odd natural number is 29

other numbers are

\red{\sf{x+2}} = 29 + 2 = 31

\red{\sf{x+4}} = 29 + 4 = 33

\red{\sf{x+6}} = 29 + 6 = 35

\red{\sf{x+8}} = 29 + 8 = 37

\gree{\underline{\sf{Verification-}}}

29 + 31 + 33 + 35 + 37

= \red{\sf{(29 + 31)}} + \blue{\sf{(33 + 35)}} + 37

= \red{\sf{60}} + \blue{\sf{68}} + 37

= \green{\sf{(60 + 68)}} + 37

= \green{\sf{128}} + 37

= \boxed{\boxed{\bf{165}}}

{\underline{\sf{Question}}}

The sum of five consecutive odd natural number is 165.what are the number

{\underline{\sf{Solution}}}

Let the first five consecutive odd numbers be x,x+2,x+4,x+6,x+8.

According to the Question:

The sum of five consecutive odd natural number is 165.then ,

x+(x+2)+(x+4)+(x+6)+(x+8)=165

5x+20=165

5x=145

x= 29

Other Number's :

x+2=29+2=31

x+4=29+4=33

x+6=29+6=35

x+8=29+8=37

\rule{200}2

Verification:

x+x+2+x+4+x+6+x+8

= 29+31+33+35+37

= 165

Hence , Proved
