Answer 1

Hey

Answer:

yea it is AP

Step-by-step explanation:

we have

a2 -a1 =8 -12 =-4

a3- a2 = 4 -8 = -4

☺

Answer 2

Yes , this is an airthmatic progression ,

As the first gap differ between 12 and 8 is equal to the gap between 8 and 4 and so on between 4 and 0.

• a1 = 12
• a2 = 8
• a3 = 4
• a4 = 0

D = a2 - a1 = a3 - a2 = a4 - a3 = - 4

• 8 - 12 = 4 - 8 = 0 - 4 = 4

Or a1 - a2 = a2 - a3 = a3 - a4 = 4

• 12 - 8 = 8 - 4 = 4 - 0 = 4
