Answer:
The explicit form for this sequence is for all
.
Step-by-step explanation:
The explicit form of an arithmetic sequence of numbers is given by the formula , where
is the first term of the sequence,
is the difference between two consecutive terms of the sequence, and
.
We know that the first four elements for the arithmetic sequence are .
To find the general formula for this problem we only need to calculate in the above formula.
For n=2, we have
if we replace and
and solve for
we obtain
Therefore the explicit form is for all
.
