Answer:

  47

Step-by-step explanation:

<u>Given</u>:

  a1 = 26, a37 = 278

<u>Find</u>:

  a4

<u>Solution</u>:

Filling in the given values in the formula for the general term of an arithmetic sequence, we have ...

  an = a1 +d(n -1)

  a37 = 26 +d(37 -1) = 278

  d = (278 -26)/36 = 7 . . . . . . solve for d

Then the 4th term is ...

  a4 = 26 +7(4 -1)

  a4 = 47

A number and it's absolute value are equal. If you subtract 2 from the number, the new number and it's absolute value are not eq
yaroslaw [1]
This means that the number is positive. 

The absolute value is the distance away from 0 the number is.

So 1's absolute value would be 1, yet -5's absolute value would be 5.

So the number that's equal to its absolute value is positive, and the one that's not is negative.

So if you subtract 2 from the positive number, it must turn negative.

So 1 is a number that satisfies these conditions.

Which of the following is equal to (2x/3 - 7) + 7
diamong [38]
<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>
