a friend sent it to me

[dreamy pumice]

hm ok

[bleak widget]

i got 11503

but its wrong

[dreamy pumice]

well show steps please

[bleak widget]

i assumed square are perfect and gave them values

1225 225

A1=a A2=ar A3=ar^2 A4=ar^3 A5=ar^4

[dreamy pumice]

erm

theyre not squares

[bleak widget]

A1 and A3

[dreamy pumice]

well

not all of them

[bleak widget]

then a=225 and r=35/15

[dreamy pumice]

well start by finding the common ratio

[bleak widget]

how

i didn’t even know what a geometric progression was

[dreamy pumice]

that would be an issue

[bleak widget]

is it r

[bleak widget]

.

[dreamy pumice]

oh yea

[bleak widget]

35/15

[dreamy pumice]

so A3-A1 = a(r^2-1)

[bleak widget]

yes

[dreamy pumice]

oh wait you cant find the common ratio

[bleak widget]

if r=35/15 then a=225

[bleak widget]

yes

[dreamy pumice]

you can find arithmetic sequence with the info x is 1000 greater than y

erm you probably have to do something with the side lenghts

just find a random equation
