The figures below show a pattern.

find the expression that could be used to determine the number of squares in the nth figure.

= 3n + 1

Step-by-step explanation:

Th number of squares in each figure is

4, 7, 10, ....

The terms have a common difference, that is

7 - 4 = 10 - 7 = 3

The number of squares in the n th figure is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 4 and d = 3, thus

= 4 + 3(n - 1) = 4 + 3n - 3 = 3n + 1

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
