Question

fill in the missing numbers to complete the pattern: 0.8, , , 1.4, 1.6, 1.8

Explanation:

Step1: Find the common difference

Look at the given numbers \(1.4\), \(1.6\), \(1.8\). The difference between consecutive terms is \(1.6 - 1.4 = 0.2\) and \(1.8 - 1.6 = 0.2\). So the common difference \(d = 0.2\).

Step2: Find the first missing number

To find the first missing number (second term), add the common difference to the first term. The first term is \(0.8\), so \(0.8 + 0.2 = 1.0\).

Step3: Find the second missing number

To find the second missing number (third term), add the common difference to the second term (which we found as \(1.0\)). So \(1.0 + 0.2 = 1.2\).

Answer:

The missing numbers are \(1.0\) and \(1.2\), so the sequence is \(0.8, 1.0, 1.2, 1.4, 1.6, 1.8\).
