I fan and medal help plzzzzzzzzzzzzz

Answer 1

so you need to identify the common ratio... so look at the terms

n = 1

\[a_{1} = -3(4)^{1 -1} = -3\]

n = 2

\[a_{2} = -3(4)^{2 -1} = -12\]

so what are you multiplying by?

Answer 2

you can, and add them all up out you can use the formula for the sum of a geometric series

Answer 3

@campbell_st

Answer 4

well if you found every term, they would all be negatives...

so adding 5 negatives will give a negative

Answer 5
