fill in the missing numbers to complete the pattern: 1.53, 1.78, _, 2.28, 2.53

Explanation:

Step1: Find the common difference

Subtract consecutive terms: $1.78 - 1.53= 0.25$.

Step2: Calculate the first - missing number

Add the common difference to the previous term. $1.78+0.25 = 2.03$.

Step3: Check the pattern for the second - missing number

Add the common difference to the first - missing number. $2.03+0.25 = 2.28$ (which is correct as per the given sequence).

Answer:

$2.03$
