If a1 = 3 and an = 5an-1 then find the value of a5.
HELP FAST PLEASE

The value of a5 is 3125

Step-by-step explanation:

Recursive Sequence

It refers to the sequences where each term is given as a rule that depends on one or more of the previous terms, unlike explicit sequences where a general term is given and we can calculate any term without knowing the value of the previous terms, except for the first one.

The sequence is given as:

a_1=5a

1

=5

a_n=-5a_{n-1}a

n

=−5a

n−1

To find the value of a5, we need to find the previous terms first:

a_2=-5a_{1}=-5*5=-25a

2

=−5a

1

=−5∗5=−25

a_3=-5a_{2}=-5*(-25)=125a

3

=−5a

2

=−5∗(−25)=125

a_4=-5a_{3}=-5*125=-625a

4

=−5a

3

=−5∗125=−625

a_5=-5a_{4}=-5*(-625)=3125a

5

=−5a

4

=−5∗(−625)=3125

The value of a5 is 3125

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

9 x 8 divided by (5-3)=36
