3n - 1

When n = 1,

3n - 1 = 3*1 - 1 = 3 -1 = 2

When n = 2,

3n - 1 = 3*2 - 1 = 6 -1 = 5

When n = 3,

3n - 1 = 3*3 - 1 = 9 -1 = 8

Hence, the first three terms are 2, 5 and 8.

BartSMP [9]

Answer:

Length\ of\ the\ long\ piece=40\ meters\\\\Length\ of\ the\ short\ piece=17\ meters

Step-by-step explanation:

Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.

Set up a system of equations:

\left \{ {{s+l=57} \atop {s=l-23}} \right.

Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":

(l-23)+l=57\\\\2l=80\\\\l=\frac{80}{2}\\\\l=40

Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:

s=40-23\\\\s=17
