Answer 1

Answer: The first 4 terms of the arithmetic sequence in the graph (1,2)(2,-2)(3,-6)(4,-10)

Explanation:

Given a graph with coordinates:

(x,y)= (1,2)(2,-2)(3,-6)(4,-10)

The sequence of values of 'x' : 1,2,3,4

For an arithmetic expression 'd' remains the same between the two consecutive terms

2-1 = 3-2 = 4-3 = 1 = d

The sequence of values of 'y' : 2,-2,-6,-10

For an arithmetic expression 'd' remains the same between the two consecutive terms

(-2)-(2) = (-6)-(-2) = (-10)-(-6) = (-4) = d

Hence, the first 4 terms of the arithmetic sequence in the graph (1,2)(2,-2)(3,-6)(4,-10)
