The nth term in a sequence is 2n -6 work out the first three terms

Mathematics
1 answer:
Nata [24]3 years ago
6 0

Answer:

The first three terms in the sequence are -4, -2, 0

Step-by-step explanation:

In any sequence n represents the position of the term in the sequence

<u><em>Examples:</em></u>

First term ⇒ n = 1

Second term ⇒ n = 2

Fifth term ⇒ n = 5

Let us solve our question

∵ The rule of the nth term is an = 2n - 6

→ We need to find the first three terms, means n = 1, 2, 3

∵ n = 1

∴ a1 = 2(1) - 6

∴ a1 = 2 - 6

∴ a1 = -4

∴ The first term is -4

∵ n = 2

∴ a2 = 2(2) - 6

∴ a2 = 4 - 6

∴ a2 = -2

∴ The second term is -2

∵ n = 3

∴ a3 = 2(3) - 6

∴ a3 = 6 - 6

∴ a3 = 0

∴ The third term is 0

The first three terms in the sequence are -4, -2, 0

Evgesh-ka [11]
It is given here that there is 1/3 probability of professional baseball player will get a hit. Hence if  at least three hits are gained out of 5 attempts, the calculation goes:  5C3* (1/3)^3*(2/3)^2 + 5C4* (1/3)^4*(2/3)^1 +5C5 *<span>(1/3)^5*(2/3)^0 equal to 0.21. </span>

Which of the following is not a promotional tactic used by a seller?
Leviafan [203]

Answer:

we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.

Hence, 'a' is the correct option.

Step-by-step explanation:

From the given options, the 'bait and switch' technique is not a promotional tactic used by a seller.

'Bait and switch' is a deceptive sale practice using which the sells try to attract (bait) the customers by offering attractive prices on certain items, but when the customers tend to go to the shop to buy the items, they witness the unavailability of the goods, or find the prices go higher compared to what they had been offered.

Now, since the customers are already present at the shop, the sellers try to pressurize the customer so that they could buy something else.

Therefore, we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.

Hence, 'a' is the correct option.

The rephrased statement for Kun's proof is: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.

<h3>What is a Parallelogram?</h3>

A parallelogram is a quadrilateral that has two opposite sides that are congruent to each other and are also parallel to each other.

This means that if two pairs of opposite sides of a quadrilateral are congruent and parallel, then it is a parallelogram.

Rephrasing Kun's statement in his proof will therefore be: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.
