Question

fill in the missing numbers to complete the pattern: , 1.22, , 2.22, 2.72, 3.22

Explanation:

Step1: Identify the pattern

Observe the given sequence: $2.22, 2.72, 3.22$. Calculate the difference between consecutive terms: $2.72 - 2.22 = 0.5$, $3.22 - 2.72 = 0.5$. The common difference is $0.5$.

Step2: Find first missing number

Subtract $0.5$ from $1.22$ to get the preceding term: $1.22 - 0.5 = 0.72$

Step3: Find second missing number

Add $0.5$ to $1.22$ to get the next term: $1.22 + 0.5 = 1.72$

Answer:

$0.72$, $1.72$
