ANSWER:
- The three consecutive odd integers are 23, 25, 27.
GIVEN:
- Sum of twice the first, the second and three times the third is 152.
TO FIND:
- The three consecutive odd integers.
EXPLANATION:
Let us take a number 2n.
n may be any natural number.
2n is absolutely even. As 2 times any number is always even.
•°• 2n + 1 will absolutely odd.
Let the cosecutive odd numbers be 2n + 1, 2n + 3, 2n + 5.
=> 2(2n + 1) + 2n + 3 + 3(2n + 5) = 152
=> 4n + 2 + 2n + 3 + 6n + 15 = 152
=> 12n + 20 = 152
=> 12n = 132
=> n = 11
First number = 2n + 1
=> Substitute n = 11
=> First number = 2(11) + 1
=> First number = 22 + 1
=> First number = 23
Second number = 2n + 3
=> Substitute n = 11
=> Second number = 2(11) + 3
=> Second number = 22 + 3
=> Second number = 25
Third number = 2n + 5
=> Substitute n = 11
=> Third number = 2(11) + 5
=>Third number = 22 + 5
=> Third number = 27
Hence the three consecutive odd integers 23, 25, 27.
