ANSWER

EXPLANATION
The explicit rule for an arithmetic sequence is given by:

It was given that:

and

The common difference is

We plug in the values into the explicit formula to get,

Expand to get,

The explicit rule is

I haven’t got there yet sorry
4 = 2/4u
Multiply both sides by 4u
16u = 2
Divide both sides by 16, and simplify.
u = 1/8
