The first five terms are: 3, 8, 13, 18, 23
This is a linear sequence
Explanation:
Plug in n = 1 to get the first term
E(n) = 5*n-2
E(1) = 5*1-2
E(1) = 3
So 3 is the first term
Do the same for n = 2 to get the second term
E(n) = 5*n-2
E(2) = 5*2-2
E(2) = 8
So 8 is the second term
And again for n = 3
E(n) = 5*n-2
E(3) = 5*3-2
E(3) = 13
This means 13 is the third term
And again for n = 4
E(n) = 5*n-2
E(4) = 5*4-2
E(4) = 18
This means 18 is the fourth term
Finally, repeat for n = 5
E(n) = 5*n-2
E(5) = 5*5 - 2
E(5) = 23
So 23 is the fifth term
This sequence is linear because we're incrementing by the same amount each time. In this case, we're adding 5 each time for the sequence 3, 8, 13, 18, 23, and so on.

30 desks
200 bookcases
Step-by-step explanation:
Hello!
To solve this problem we must propose 2 linear equations as follows.
1.for the cutting time = if we multiply the number of desks (D) by the cutting time (5h) plus the number of bookcases (B) by the cutting time (15min = 0.25h), it will result in the Total available cutting time = 200h
1.For the time of the assembly = if we multiply the number of desks (D) by the time of assembly (10h) plus the number of bookcases (B) by the time of assembly (1h), it will result in the total time available of assembly = 500h.
taking into account the above we infer the following equations
5D+0.25B=200 (ecuation number 1)
10D+B=500 (ecuation number 2)
Now what we have to do is solve the system of two linear equations and two unknowns, for which we will take equation number 1 multiply it by four and subtract equation 2, then apply algebra
4(1)-(2)
20D+B=800
-
10D+B=500
---------------------------
10D=300
Now we use equation number 2 to find the number of book cases
10D+B=500
B=500-10D
B=500-10(30)=200bookcases
