The <u><em>correct answer</em></u> is:
0.6 + 0.02 + 0.004
Explanation:
To write a number in expanded form, we use place value. In this number, 6 is in the tenths place; that makes its value 6(0.1) = 0.6.
2 is in the hundredths place; that makes its value 2(0.01) = 0.02.
4 is in the thousandths place; that makes its value 4(0.001) = 0.004.
Together, we get a sum of 0.6+0.02+0.004.
The explicit rule for given sequence is:

Further explanation:
We have to determine first of all if the sequence is arithmetic or geometric.
- If the difference of two consecutive terms is same then the sequence is arithmetic sequence
- If the ratio of two consecutive terms is same then the sequence is geometric sequence
Given sequence is:
12,22,32,42

The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:

Putting the values of a1 and d
