The term-to term of the sequence is multiply by 2 and add 3

the third term is 17

what is the first


---- ---- 17 just the first on please ;D I WILL MARK AS BRAINIEST PLEASE HAHAHAHHA

Answers

Answer 1
Answer:

It is given that the third terms is obtained by multiplying the second term by 2 and then adding 3:

a_3 = 2a_2+3

Since the third term is 17, we have

17=2a_2+3 \iff 2a_2=14\iff a_2=7

And then again, the second term is obtained by multiplying the first one by 2 and then adding three:

a_2 = 7 = 2a_1+3

Solve this equation for a_1 and you'll get the answer

5z – 8 = 32 please answer

Answers

add 8 to both sides
5z = 40
divide both sides with 5
z = 8
Z=8 

The reason i know this is:
5z-8=32     add 8 to both sides
5z - 8 = 32
    + 8    +8 (the -8+ 8 get taken off.)
So you have left 
5z=40
divide
5z       =     40
----            ------
5                  5
the 5's get crossed out 
and divide 40 by 5 and you'll get 8 :)
