1) -24, -4, 16, 36, ...<br> Find a23
viktelen [127]

We're given the Arithmetic Progression <em>-24, -4, 16, 36 ...</em> .

We know that a term in an AP is generally represented as:

\bf a_n\ =\ a\ +\ (n\ -\ 1)d

where,

  • a = the first term in the sequence
  • n = the number of the term/number of terms
  • d = difference between two terms

We need to find \sf a_2_3.

From the given progression, we have:

  • a = -24
  • n = 23
  • d = (-24 - (-4) = -20

Using these in the formula,

\sf a_2_3\ =\ a\ +\ (n\ -\ 1)d\\\\\\a_2_3\ =\ -24\ +\ (23\ -\ 1)\ \times\ (-20)\\\\\\a_2_3\ =\ -24\ +\ 22\ \times (-20)\\\\\\a_2_3\ =\ -24\ -\ 440\\\\\\\bf a_2_3\ =\ -464

Therefore, the 23rd term in the AP is -464.

Hope it helps. :)

Write equation of a line perpendicular to the y-axis that passes through the point (-4,-8)
babymother [125]

Answer:

y = -8

Step-by-step explanation:

Since the line is perpendicular to the y-axis, it will be a horizontal line that runs through (-4,-8).

When a line is perpendicular to the y-axis, the x-coordinate doesn't matter because the line will be horizontal, meaning it will be the same y value regardless of the x value. In this case, the y value is −8 throughout the line.
