1.)given the recursive definition latex: a_{n+1}=2\cdot a_n+1a n + 1 = 2 ⋅ a n + 1, and that latex: a_1=1a 1 = 1, find latex: a_{10}a 10

group of answer choices

2.)given the explicit definition: latex: t_n=n^2-2nt n = n 2 − 2 n, find latex: t_4

1) 1023

2) 8

Step-by-step explanation:

1)

Given:

and

Then,  the next table can be computed (only the first terms are explicitely shown)

n      

1       1

2       3

3      7

4      15

5      31

6      63

7      127

8      255

9      511

10     1023

2)

Given

Then,  the next table can be computed

n      

1       -1

2      0

3      3

4      8

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
