well for the first one...i came up with
a sub n= 28,200x(.1) to the (n-1) power
is that right?
a sub n= 28,200x(.1) to the (n-1) power
is that right?

Ah, your monthly salary is 28,200/12 and it is the monthly, not yearly figure you need for the first part.

Now we all wish it worked by a power law like that but unfortunately it is just the same amount every month
that amount the first month
that again for a total of 2 thats
that a third time for a total of 3 thats
that amount the first month
that again for a total of 2 thats
that a third time for a total of 3 thats

Now do the second part the same way, except now it does indeed go by years.
Again it increases by a constant amount every time period, not by a percentage of the previous amount. That makes it much simpler than it would be otherwise.

okay so if it says ...how much will u have ontributed to the plan after 6 months...should i do:
28,200/12 x (.1)to the n-1 power
or should i not divide by 12?
28,200/12 x (.1)to the n-1 power
or should i not divide by 12?

It is not to the power at all
it is just the number of month times the contribution every month which is 2350 times n
it is just the number of month times the contribution every month which is 2350 times n

Now the second one is the same theory, again nothing to a power.
first column year
second column salary
1 28,200 salary increases by $1400 each year.
2 28200+ 1400=29600
3 28200+ 2*1400 =31000
4 28200+ 3*1400 =32400
....
n 28200+(n-1)*(1400)
first column year
second column salary
1 28,200 salary increases by $1400 each year.
2 28200+ 1400=29600
3 28200+ 2*1400 =31000
4 28200+ 3*1400 =32400
....
n 28200+(n-1)*(1400)
