Solve for the sum of all positive integers, from 5 to 1255, that can be divided by 5.

The sum of all the numbers which are multiple of 5 between 5 an 1255 is 158,130

Step-by-step explanation:

In this question, we are asked to calculate the sum of all positive numbers that can be divided by 5 between 5 and 1255

To calculate this, we make use of the sum of an arithmetic progression

Mathematically, we have this as

Sn = n/2[a + L]

Where n is the number of terms which we do not know yet

a is the first term which is 5 and L is the last term which is 1255

Now to get n, we make use of the formula for finding the nth term of an arithmetic sequence

Tn = a+(n-1)d

where a is the first term which is 5 and d is the common difference which is also 5 with our Tn which is 1255

Substituting these values into the last term equation, we have

1255 = 5 + (n-1)5

1255 = 5 + 5n - 5

5n = 1255

n = 1255/5

n = 251

This means the number of terms we have in this arithmetic series is 251

Now we plug this n value into the sum equation

Thus,

Sn = 251/2(5 + 1255)

Sn = 251/2(1260)

Sn = 251 * 630

Sn = 158,130

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
