                Reiny can you please help with these 3 problem. 1. a1=-4;an-1-3 this is find the first five terms of the recursively defined sequence. Problem 2 and 3 is write the first terms of the explicitly defined sequence an=4n+2. problem 3 an=2(-3)n-1

    You seem to be persistent in writing your problem in a way that makes no sense.
Again, I will assume you mean:
a(1) = -4
a(n) = a(n-1) - 3
often this is written with subscripts
a<sub>1</sub> = -4
a<sub>n</sub> = a<sub>n-1</sub> - 3
so
a<sub>1</sub> = -4
a<sub>2</sub> = a<sub>1</sub> - 3 = -4-3 = -7
a<sub>3</sub> = a<sub>2</sub> - 3 = -7-3 = =10
continue this pattern for 2 more terms
problems 2 and 3 make no sense to me
I thought these were recursively defined sequences. In that case the initial term must be defined, since each new term is found from its previous term.
With no brackets, who can tell what they mean.

    problem 2 and problem 3 is to write the first terms of the explicitly defined sequences. problem 2: a(n)=4n+2. and problem 3: a(n)=2(-3)n-1.
