The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7

<h3>The dimension of the matrix?</h3>

From the figure in the question, we have the following highlights:

The matrix has 3 rows
The matrix has 3 columns

The dimensions of a matrix are represented by: Row by column

Hence, the dimensions of the matrix are 3 by 3

<h3>The indicated element</h3>

This is given as:

a₂₃

This means that the element is located at the second row and the third column.

The element at this position is -7

Hence, the indicated element is -7

Answer:

Step-by-step explanation:

Now to find the sum of first 20 terms, substitute n=20,a=−1 and d=4 in S n = 2n [2a+ (n−1)d] as follows: S 20 = 220 [(2×−1)+(20−1)4]=10[−2+(19×4)]=10(−2+76)=10×74=740 Hence, the sum of first 20 terms is 740.
