The first four terms of a sequence are shown below:
7, 4, 1, -2
Which of the following functions best defines this sequence?
a) f(1)=7, f(n+1) = f(n)+3; for n or equal to 1
b) f(1)=7, f(n+1)=f(n)-3; for n or equal to 1
c) f(1)=7, f(n+1)=f(n)-4; for n or equal to 1
d) f(1)=7, f(n+1)= f(n)+4 for n or equal to 1

@Nnesha  I hate to bother you again but could you please help with my last question?

anonymous · Answer

Im just over all very confused...

hartnn · Answer

can you find any pattern in your sequence ?

anonymous · Answer

they all -3

anonymous · Answer

SO B :D

hartnn · Answer

you mean
'every next term is 3 lesser than the current term'
?

anonymous · Answer

yes!

hartnn · Answer

next term : f(n+1)
current term : f(n)

every next term is 3 lesser than the current term
f(n+1) = f(n) -3

yes, B :)
