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. :)

Multiply and simplify: –3x2y2 • x4<br> –3x5y2<br><br> 9x5y2<br><br> –3x6y2<br><br> –3x5y6
Contact [7]

Answer:

Multiplying and simplifying the term -3x^2y^2 \:.\: x^4 we get \mathbf{-3x^6y^2}

Option C is correct option.

Step-by-step explanation:

We need to multiply and simplify: -3x^2y^2 \:.\: x^4

Simplifying the term:

-3x^2y^2 \:.\: x^4

While multiplying, the variables with same bases are multiplied: a^m\:.\:a^n=a^{m+n}

In the given question only x^2 and x^4 are variables with same bases, So we get:

=-3(x^{2+4})y^2\\=-3x^6y^2

So, multiplying and simplifying the term -3x^2y^2 \:.\: x^4 we get \mathbf{-3x^6y^2}

Option C is correct option.
