Question

The sum of 5 consecutive odd numbers is 145 what is the third number in this sequence

Answer 1

The order is 25,27,29,31,33 so the third number is 29.

Answer 2

let nos be x,x+2,x+4,x+6,x+8

so sum is 145

x+ x+2 + x+4+x+6+x+8 = 145

5x + 20 = 145
5x = 125
x = 25

third no is x+4 = 25 +4 = 29
