Letters a, b, c, and d are angle measures. Which should equal 105° to prove that f ∥ g? abcd

Bess [88]

we know that

If lines f and g are parallel

then

the angle c must be equal to

∠c= $75\°$ ------> by alternate exterior angles

and

∠c+∠d= $180\°$ ------> by supplementary angles

∠d= $105\°$

therefore

the answer is

The angle d should be equal to $105\°$ to prove that f ∥ g

For the Sequence 2,6,10,14. Write the recursive rule, and a explicit rule

Evgen [1.6K]

Answer:

The recursive formula for given series is: $a_{n} = a_{n-1} + 4$

The explicit formula is given by: $a_{n} = 10 + 5(n-1)$

Step-by-step explanation:

Determining the Recursive Formula:

As the given sequence is: 2,6,10,14

The difference d can be computed by taking the difference between the consecutive terms of the mentioned sequence.

d = 6 -2 = 10 - 6 = 14 - 10 = 4

It is observed that the difference between the consecutive terms remains constant) with common difference d = 4
We know that if the difference between the consecutive terms remains constant), then the series is in arithmetic series. The recursive formula is: $a_{n} = a_{n-1} + d$

So, the recursive formula for given series is: $a_{n} = a_{n-1} + 4$

Determining the Explicit Rule or Formula:

An explicit formula defines the nth term of the sequence, where n being the term's location. In other words, a sequence can be defined as a formula in terms of n. So,

First determine the sequence whether the sequence is in arithmetic. As we know that 2,6,10,14 is in arithmetic.
Then find the common difference. Here, d = 6 -2 = 10 - 6 = 14 - 10 = 4
Establishing an explicit formula by analyzing the pattern. i.e. adding first term to the product of d (common difference) and one less than the term number

Hence, the explicit formula is given by:

$a_{n} = a_{1} + d (n-1)$

where,

aₙ is the nth term of the sequence

n is the term number

a₁ is the first term

d is the common difference

As the given sequence is: 2,6,10,14

a₁ = first term = 2

d = common difference = 6 - 2 = 4

Using explicit formula:

$a_{n} = a_{1} + d (n-1)$

$a_{n} = 10 + 5(n-1)$

$a_{n} = 10 + 5n-5$

$a_{n} = 5n+ 5$
