Look at the sequence in the table.
.
which recursive formula represents the sequence shown?
a) an=an-1+5
b) an= 2an-1 +1
c) an= 3an-1 -1
d) an= 5an-1 +1

A

Step-by-step explanation:

The consecutive values of have a common difference d, that is

d = 8 - 3 = 13 - 8 = 18 - 13 = 23 - 18 = 5

This indicates that the sequence is arithmetic.

The recursive formula allows the next term in the sequence to be found from the previous term by adding 5, thus

= + 5 → A

(-1,-0.5)

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
