Question

The average of 44 consecutive odd numbers is 144 what is the largest number

Answer 1

Answer:

Let the first number be = x

Other numbers = x + 1, x + 3... x + 89

Average :

$\tt{\frac {x+x+1+x+3...+x+89}{44} = 144}$

=> 44x + 1936 = 6336

=> 44x = 6336 - 1936

=> x = 100

Largest number = 100 + 89 = 189
