Explain how to write the explicit rule for the arithmetic sequence from the given information

The rule shows that each term is 8 more than the previous term, so the common difference is 8 . The explicit formula of an arithmetic sequence is the initial term plus (n – 1)d.  The explicit rule for this function can be found by substituting 42 for a1 and 8 for d.  The explicit rule for the sequence is

42 + (n – 1)8.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
