Question

The sum of five consecutive odd natural numbers is 65. Find the sum of extreme numbers.​

Answer 1

Answer:

let the first odd no. be = x

let the second odd no. be = x+1

let the third odd no. be = x+3

let the fourth odd no. be = x+5

let the fifth odd no. be = x+7

sum of these no. = 65

x+x+1+x+3+x+5+x+7=65

5x+16=65

5x=65-16

5x=49

x=49/5
