Find the explicit formula for the arithmetic sequence -31,-27,-23,-19 b(n)= ?

7x+8y=-18, 4x-9y=-3 solve the system of equations

Asequence is defined recursively by the formula  f(n  +  1)  =  f(n)  +  3 . the first term of the sequence is  –4. what is the next term in the sequence? –7–117

Can someone me and plz do the problem
