Help me with this question of O math​

2. A mathematical sequence is an ordered list of objects, often numbers. Sometimes the numbers in a sequence are defined in terms of a previous number in the list. A sequence is an ordered list of numbers . In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on. ... The notation a 1, a 2, a 3,… a n is used to denote the different terms in a sequence.

5) A square matrix is a special type of matrix in which the number of rows is equal to the number of columns. If a square matrix has $ n $ rows and $ n $ columns, it is said to be of the order $ n $.

Aesthetically, as the name suggests, the matrix looks like a square. Square matrices can be of the order $ 1 $, $ 2 $, or any number, $ n $. Theoretically we can have a square matrix of the order $ 100 $! But practically, it is tough to work with square matrices of order $ 11 $ and above.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
