Question

the sum of 5 consecutive odd numbers is 135, what is the secound number in this sequence

Answer 1

Hi there!
Here's the answer:

Let the 5 consecutive odd No.s be x,x+2,x+4,x+6,x+8
Given they sum up to 135
x+x+2+x+4+x+6+x+8= 135
=> 5x+20= 135
=> 5x= 115
=> x= 23

•°• Second No. in the sequence is x+2= 23+2= 25

$let 5 consecutive odd numbers be x,x+2,x+4,x+6,x+8$

$x+x+2+x+4+x+6+x+8 = 135$

$5x+20=135$

$5x=135-20$

$x=115/5$

$x=23$

$1no.=x=23$

$2nd no.=x+2=25$

$3rd no. =x+4=27$

$4th no. =x+6=29$

$5th no. =x+8=31$
