To add matrices, add the terms in the corresponding boxes. The resulting matrix will be your answer:

\left[\begin{array}{ccc}-8&-1&7\\0&9&2\end{array}\right] +   \left[\begin{array}{ccc}-2&0&-2\\-4&5&-1\end{array}\right] =   \left[\begin{array}{ccc}-10&-1&5\\-4&14&1\end{array}\right]

Write the first five terms of the sequence in which the nth term is
ziro4ka [17]

Answer:

C) 2,6,24,120,720

Step-by-step explanation:

Here the n-th term An = \frac{(n +2)!}{n + 2}

A1 is the first term

A1 = (1 + 2)!/(1 + 2)

= 3!/3

A1 = 2

A2 is the second term

A2 = (2 +2)!/(2 +2)

= 4!/4

A2 = (1*2*3*4) /4

A2 = 6

A3 is the third term

A3 = (3 + 2)!/(3 +2)

A3 = 5!/5

A3 = 24

A4 is the fourth term

A4 = (4 + 2)!/(4 + 2)

A4 = 6!/6

A4 = 120

A5 is the fifth term

A5 = (5 + 2)!/(5 +2)

A5 = 7!/7

A5 = 720

Answer: C) 2,6,24,120,720
