Question

The sum of 7 consecutive odd numbers is 133. What is the largest of them?

Answer 1

Answer:

Step-by-step explanation:

X = smallest of the 7 consecutive odd number

x + 2 = second

x + 4 = third

...

x + 12 = seventh

x + 2 + x + 4 ... + x + 12 = 133

7x = 133 - 42

7x ÷ 7 = 91 ÷ 7

x = 13 - first

x + 2 = 13 + 2 = 15 - second

...

x + 12 = 13 + 12 = 25 - seventh

Therefore, the answer to your question is 25.

The numbers are 13, 15, 17, 19, 21, 23, 25.
