# Read the numbers and decide what the next number should be. 1, 1.25, 7, 7.50, 2, 2.25, 8,…?

**Solution:**

Given the sequence is 1, 1.25, 7, 7.50, 2, 2.25, 8,…

The difference between the first term and the second term is 0.25

Then 5.75 is added to the second term, we got the third term

Then, 0.5 is added we got the fourth term

The term ‘2’ is formed by subtracting ‘5.5’

Again the next term is formed by adding 0.25

Hence,the sequence of addition and subtraction is +0.25 -- +5.75 -- + 0.50 -- -5.5 -- + 0.25 -- + 5.75

So the next number must be 8 + 0.50 = 8.5

## Read the numbers and decide what the next number should be. 1, 1.25, 7, 7.50, 2, 2.25, 8,…?

**Summary:**

In the series 1, 1.25, 7, 7.50, 2, 2.25, 8,… the next term is 8.5
