Question

The seven numbers 1, 2, 5, 10, 25, 50, 100 repeat to form the following pattern.

1, 2, 5, 10, 25, 50, 100, 1, 2, 5, 10, 25, 50, 100

What is the 75th number in the pattern? How did you get the answer?

Answer 1

25

Explanation:

First number = 1

Second number = 2

Third number = 5

Fourth number = 10

Fifth number = 25

Sixth number = 50

Seventh number = 100

Again 14th number will be = 100

Again 21st number will be = 100

Continuing 70 th number will be = 100

71st number= 1

72nd number = 2

73rd number = 5

74th number = 10

75th number = 25

OR

`(75)/(7) = 10 * 7 + 5\\`

So, after repeating 10 times up to 100, then the 5 number will be the 75th number , which is 25
