PLEASE HELP!
Question an answers in screenshot

Answer 1

generalexplicit formula for nth term of a GS is a1r^(n-1)

wher a1 = first term and r = common ratio

you can find r by dividing the second term by the first term

Answer 2

so here r = -0.06 / 0.2

Answer 3

@lilkg77 are you here again please ?

Answer 4

from these choices for n=1 where you get a_1 = 0,2
like a little help attention that for n=1 the second term has exponent zero what mean - what ?

Answer 5

Have you already figured it out

Answer 6

No @Daniel56k

Answer 7

Sorry @jhonyy9

Answer 8

Alright i got u

Answer 9

Now am 100% sure that you know the formula for A.P

Answer 10

\[nth=a(n-1)d\]

Answer 11

Yes i know the formula @Daniel56k

Answer 12

a= first term
d= change in first and second term

Answer 13

am a 9th grader am use to breaking things down...am very sorry lets just go straight to the point if you are cool with that

Answer 14

\[a _{n}=ar ^{n-1}\]

Answer 15

formula for geometric sequence

Answer 16

are you with me

Answer 17

Yes @Daniel56k

Answer 18

okay to find r which is called common ratio or what ever you think it is just divide the first term from the second term

Answer 19

are you with me
