Question

Type the missing number in the sequence

Answer 1

Answer: 10

Explanation:

1, 10, 100, 1,000, etc.

The formula is 1/10 if you’re going left or 10/1 if you are going right.

The fourth term is 10,000, the third term is 1,000, the second term is 100, so the first term has to be 10

100 / 10 = 10

Answer 2

10

Explanation:

Take the third term and divide by the second term

1000/100 = 10 which is the common ratio

To find the first term divide by the common ratio

100/10 = 10

The first term is 10
