Answer:

167 people spoke truth

Step-by-step explanation:

Five hundred children took turns to say a prayer the first said two plus two is four the second said two plus two is five each of the others when his turn came said the two previous people lied how many people told the truth?

1st Said 2 + 2 = 4     TRUE

2nd Said  2 + 2 = 5   LIE

3rd said  the two previous people lied = LIE   ( as First said True)

4th said  the two previous people lied = TRUE   ( as 2nd & 3rd Lied)

5th said  the two previous people lied = LIE   ( as 4th said True)

6th said  the two previous people lied = LIE   ( as 4th said True)

7th said  the two previous people lied = TRUE   ( as 5th & 6th Lied)

this sequence will continue

People who spoke Truth

1 , 4 , 7 , 10 , .........................................................., 496 , 499

499 = 1 + (n-1)3

=> n-1 = 166

=> n = 167

167 people spoke truth
