Whats the mising number in this sequence?

88511, 16351, ?, 10251

The missing number in the sequence is 73155.

Step-by-step explanation:

To solve this question, we have to find patterns in the numbers.

The number 16351 was generated from a pattern in the number 88511. What pattern?

8 + 8 = 16

So adding the first two digits of the first number, we get the first two digits of the second number

8 - 5 = 3

Subtracting the second and the third digit of the first number, we get the third digit of the second number.

5*1 = 5

Multiplying the third and the fourth digit of the first number, we get the fourth digit of the second number.

1/1 = 1

Dividing the fourth and the fifth digit of the first number, we get the fifth digit of the second number.

Third number

Just like we applied the patterns on the first number to get the second, we can apply the patterns on the second to get the third. So

1 + 6 = 7

6 - 3 = 3

3*5 = 15

5/1 = 5

So

The missing number is 73155.

Confirmation: Third and fourth number:

7 + 3 = 10

3 - 1 = 2

1 * 5 = 5

5/5 = 1

Which shows that the third number is, in fact, 73155

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
