Question

The average of 5 consecutive odd numbers is
85. What is the 1st number?​

Answer 1

Answer:

83

Step-by-step explanation:

the five consecutive numbers whose average is 85 are 83, 84, 85, 86, 87

Answer 2

Let the first number be 'z'

Then, the numbers are, z , (z+1) , (z+2) , (z+3) , (z+4)

Adding all the numbers , we get, z+z+1+z+2+z+3+z+4

                                                 = 5z + 10

ATQ; (5z + 10)/5 = 85

=> 5z + 10 = 425

=> 5z = 415

=> z = 83

Therefore the first no. is 83
