1. Problem Description

The problem states that the sum of 5 consecutive odd integers is
7

5. We need to find the largest of these 5 integers.

2. Solution Steps

Let nn be the first odd integer. Since the integers are consecutive odd integers, the other four integers are n+2n+2, n+4n+4, n+6n+6, and n+8n+8. The sum of these five integers is given as
7

5. Therefore, we can write the equation:

n+(n+2)+(n+4)+(n+6)+(n+8)=75n + (n+2) + (n+4) + (n+6) + (n+8) = 75
Combining like terms, we have:
5n+20=755n + 20 = 75
Subtracting 20 from both sides:
5n=75205n = 75 - 20
5n=555n = 55
Dividing both sides by 5:
n=555n = \frac{55}{5}
n=11n = 11
Now we find the five consecutive odd integers:
n=11n = 11
n+2=11+2=13n+2 = 11+2 = 13
n+4=11+4=15n+4 = 11+4 = 15
n+6=11+6=17n+6 = 11+6 = 17
n+8=11+8=19n+8 = 11+8 = 19
The five consecutive odd integers are 11, 13, 15, 17, and
1

9. The largest of these is

1
9.

3. Final Answer

19
