Can someone write an explicit formula for the following sequence for me? :
3, -4, -11, - the d=-7.

Step-by-step explanation:

The explicit form for an arithmetic sequence is:

where is the first term and [ted]d[/tex] is the common difference.

The given sequence is arithmetic because term-previous term is the same per each pair of term and previous term.

That is the following holds:

-4-3=-11-(-4)=-18-(-11)

All of these differences are equal to -7, the common difference.

So let's fill in the explicit form:

5y-4 does not equal -5y+4
