Here's another problem
The number of homes sold is growing according to a linear growth model. The first week 4 homes were sold (P0=4) The second week a total of 10 homes were sold. (P1=10)
n=01st week po=4 p1=10 d=6
n=12nd week d=p1p0=104=6
Write the recursive Formula for the number of homes sold
pn in the (n+1)th week pn=pn1+6
Write the explicit Formula for the number of homes sold
Pn in the (n+1)th week Pn=4+6n
If this trend continues how may homes will be sold in the 5th week?
n=4 5th week
P4=4+6(4)=24+4=28 homes sold in the 5th week.
How did they get this answer of 28 if its the 5th week. because it seems it should be p4= 4+6(5)= 34 Please some body answer how they got this.
