What is the sum of the arithmetic series 18 t=1 (3t-4)

PolarNik [594]

Consider the arithmetic series $_{t=1}\Sigma^{t=18} (3t-4)$

Let t=1 in the given series, we get

first term = $a_{1}$ = 3-4 = -1.

Let t=2 in the given series, we get

second term = $a_{2}$ = $(3 \times 2)-4 = 2$

Let t=3 in the given series, we get

third term = $a_{3} = (3 \times 3)-4=5$

Now, let t=18 in the given series, we get

last term = l = $l = (3 \times 18)-4 = 50$

We get the series as

-1, 2, 5,..... 50

Sum = $\frac{n}{2}(a+l)$

= $\frac{18}{2}(-1+50)$

= $= 9 \times 49$

= 441

Therefore, the sum of the given arithmetic series is 441.

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday

= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold = 2 times the number of adult tickets sold on Friday

= 1,678 x 2 = 3,356

Children's Tickets sold = 3 times the number of children's tickets sold on Friday.

= 976 x 3 = 2, 928

So, the total number of tickets sold on Saturday

= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 + 6, 284 = 8,938

Hence, total number of tickets sold over these two days is 8,938.
