A sequence can be generated by using an = an-1 + 4, where a1 = 6 and n is a whole number greater than 1. What are the first four

Firlakuza [10]

Answer:

The first four terms are 4,8,12,16

Step-by-Step Explanation:

The given relation between the nth term and it's previous term is given by:

$\boxed{an = an - 1 + 4}$

GiveN:

a1 = 4

Now finding the other three terms of the AP with the given relation.

$a2 = a1 + 4$

Putting a1 = 4,

$a2 = 4 + 4 = 8$

Now, Third term:

$a3 = a2 + 4$

Putting a2 = 8,

$a3 = 8 + 4 = 12$

Now, Fourth term:

$a4 = a3 + 4$

Putting a3 = 12,

$a4 = 12 + 4 = 16$

Hence, The first four terms of the AP is 4, 8, 12 & 16.

PLEASE HELP 100 POINTS write an equation of the horizontal line that passes through (-7,-10)

Vedmedyk [2.9K]

Answer:

y + 10 = 0

Step-by-step explanation:

Slope of horizontal line is zero (0)

m = 0

By point slope form of a line.

$y-y_1 =m(x - x_1) \\ \\ y - ( - 10) = 0 \{x - ( - 7) \} \\ \\ y + 10 = 0 \{x + 7\} \\ \\y + 10 = 0 \\ \\$

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situa

Lina20 [59]

Answer:

$Expression = x + 150 +(- 26)$

$124 higher

Step-by-step explanation:

Given

$Deposit = \$150$

$Withdrawal = \$26$

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

$Balance = x + 150$

When he withdrew, the balance becomes

$Balance = x + 150 + (-26)$

Hence, the algebraic expression is

$Expression = x + 150 +(- 26)$

Calculating how much higher or lower

$Balance = x + 150 + (-26)$

Open bracket

$Balance = x + 150 -26$

$Balance = x + 124$

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

$Difference = x + 124 - x$

$Difference = \$124$

Hence, the account has a higher of $124 after both transactions
