Amusic concert is organized at a memorial auditorium. the first row of the auditorium has 16 seats, he second row has 24 seats, the third row has 32 seats, and so on increasing by 8 each row for a total of 50 rows. a) write an equation for the nth term in the arithmetic sequence b) using the equation find the number of people that can be accommodated in the 16th row

(a)  8n + 8

(b) 136

Step-by-step explanation:

No. of seats in first row = 16

No. of seats in second row = 24

no. of seats in third row = 32

Total number of rows = 50

It forms an arithmetic progression

First term = a = 16

common difference, d = 8

Number of terms, n = 50

(A) The formula for the n th term of an arithmetic progression is given by

Tn = a + (n - 1) d

Tn = 16 + (n-1) 8

Tn = 16 + 8n - 8

Tn = 8n + 8

(B) Now, n = 16

The number of seats in 16 th row is given by

T(16) = 8 x 16 + 8

T(16) = 136 seats

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
