Question

What is the average of 7 numbers preceding 7 each decreasing by 1 upon 2

Answer 1

Answer:

5

Step-by-step explanation:

Cool. Thats a good question....

Its specified that,

• 7 numbers preceding 7

so, 7 is not included.

Hence, the first number is 7 - 1/2 = 6.5

Similiarily, second number = 6.5 - 0.5 = 6

                 third number = 6 - 0.5 = 5.5...........and so on

Thus, the numbers become,

6.5, 6.0, 5.5, 5.0. 4.5, 4.0, 3.5

Now,

• sum = 6.5+6+5.5+5+4.5+4+3.5 = 35

average = sum / total number of quantities

              = 35/7

              =5
