Does the following infinite series converge or diverge? Explain your answer.
7 + 28 + 112 + 448 +...
It converges; it does not have a sum.

It diverges; it has a sum.
It diverges; it does not have a sum.
It converges; it has a sum.

It diverges; it does not have a sum.

Step-by-step explanation:

7 + 28 + 112 + 448 +...

Since the numbers keep getting larger and the ratio is greater than 1, the series will diverge

r = 28/7 = 4

correct answer:

b.(19,-2)

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
