Fifty thousand pounds is written in numbers as £50,000.
The sum of the first 10 natural numbers is 51, with an average of 5.1
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
The answer is one million (the average of the first n odd numbers is always n.)
The average of the first 91 natural numbers can be calculated using the formula for the average of the first ( n ) natural numbers, which is given by ( \text{Average} = \frac{n(n + 1)}{2n} ). For ( n = 91 ), the sum of the first 91 natural numbers is ( \frac{91 \times 92}{2} = 4186 ). Dividing this sum by 91 gives an average of ( \frac{4186}{91} = 46 ). Therefore, the average of the first 91 natural numbers is 46.
One thousand and fifty pounds, in numbers is £1050
