## 1. How Many Balls?

## 2. Guess the next number in the series

## 3. Guess the next number in the series

## 1. Answer to How Many Balls Riddle.

If you count just the balls that u see your answer would be wrong.

You have to actually count all the balls in the pyramid.

Simple way is to count the balls in each level.

So lower most level lets say 1st level has 4 x 4 balls; i.e. 16 balls

Similarly 2nd level has 3 x 3 balls; i.e. 9 balls.

3rd level has 2 x 2 balls; i.e. 4 balls.

The top most level has just 1 ball.

So the total number of balls is 16+9+4+1 = 30.

**So the image has 30 Balls** in all.

## 2. Answer to Guess the next number in the series

If you look at the series it shouldnâ€™t be that difficult.

A quick scroll through the series and you will realize the last digit on the number on the left hand side is equal to the first digit of the number on the right hand side;

Like 1,2,3,4,5 and 6.

The 2^{nd} digit is an addition of all the digits on the left hand side.

So the complete series is as follows;

111 = 13

112 = 24

113 = 35

114 = 46

115 = 57

116 = 68

**117 = 79**

## 3. Guess the next number in the series

The Math quiz is based on multiplication.

The result is the outcome of the multiplication of the number and the number below it.

So basically n x (n-1) is the series formula.

So the complete series would go as;

9 x 8 = 72

8 x 7 = 56

7 x 6 = 42

6 x 5 = 30

5 x 4 = 20

4 x 3 = 12

**3 x 2 = 6**

**Hence the last number in the series is 6**

6
