#1**+2 **

First one

Evaluate (7)^2 - 3

Second one

Evaluate 3 + 7(8)

Last one......an arithmetic sequence always has the same difference between successive terms

That is

(term two - term one) = ( term three - term two) = ( term four - term three) ......etc....

Which one of these fit the bill ???
