Question

fill in the missing numbers to complete the pattern:
□, 3.9,
□, 4.3, 4.5, 4.7

Explanation:

Step1: Identify the pattern

Observe the given sequence: $4.3, 4.5, 4.7$. Calculate the difference between consecutive terms: $4.5 - 4.3 = 0.2$, $4.7 - 4.5 = 0.2$. The common difference is $0.2$, so the sequence increases by $0.2$ each time.

Step2: Find first missing number

The term before $3.9$ is $3.9 - 0.2 = 3.7$.

Step3: Find second missing number

The term after $3.9$ is $3.9 + 0.2 = 4.1$.

Answer:

$3.7$, $4.1$
