Peter says, "If you subtract 16 from my number and multiply the difference by - 2, the result is
Ganezh [65]
Let’s say Peter’s number is P.

P minus 16 and the answer times -2 is -34

-2(P-16) = -34

-2P+32 = -34

-2P = -66

Divide by -2

P is 33.

Check: 33-16 is 17 and 17*-2 is -34. So

P is 33.

Please help me, I’ve literally been trying for so long.

Let the cosecutive numbers be like this :

2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5

Odd , Even , Odd , Even , Odd

______________________________

So we have :

(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39

6n + 9 = 4n + 6 + 39

6n + 9 = 4n + 45

Subtract both sides 9

6n + 9 - 9 = 4n + 45 - 9

6n + 0 = 4n + 36

6n = 4n + 36

Subtract both sides 4n

6n - 4n = 4n - 4n + 36

2n = 0 + 36

2n = 36

Divide both sides by 2

2n ÷ 2 = 36 ÷ 2

<em>n</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em> </em>

______________________________

So the numbers are :

2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5

36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5

37 , 38 , 39 , 40 , 41

As u can see the Odd numbers are :

37 , 39 , 41

And we're done ...
