Question

Mark the group that maintains the veracity.

Video Solution

Solution Steps

00:00 Mark the group that is a sequence
00:03 Let's try to find the pattern in each group
00:07 In this group the pattern is not constant, therefore it's not a sequence
00:19 In this group the pattern is constant, add 4, therefore it's a sequence
00:29 In this group the pattern is not constant, therefore it's not a sequence
00:33 Also in this group the pattern is not constant, therefore it's not a sequence
00:38 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the type of sequence for each option.
  • Step 2: Apply the pattern to see if it holds throughout the group.

Now, let's analyze each choice:

Option 1: 10,4,3,2,1,310, 4, 3, 2, 1, 3
The differences between each consecutive term are: 410=64 - 10 = -6, 34=13 - 4 = -1, 23=12 - 3 = -1, 12=11 - 2 = -1, 31=23 - 1 = 2.
These differences are not consistent, indicating no consistent pattern. Thus, this is not an arithmetic sequence.

Option 2: 62,58,54,50,46,4262, 58, 54, 50, 46, 42
The differences between each consecutive term are: 5862=458 - 62 = -4, 5458=454 - 58 = -4, 5054=450 - 54 = -4, 4650=446 - 50 = -4, 4246=442 - 46 = -4.
These differences are all consistent, indicating an arithmetic sequence with a common difference of 4 -4 .

Option 3: 13,9,10,10,10,113, 9, 10, 10, 10, 1
The differences between each consecutive term are: 913=49 - 13 = -4, 109=110 - 9 = 1, 1010=010 - 10 = 0, 1010=010 - 10 = 0, 110=91 - 10 = -9.
These differences are not consistent, indicating no consistent pattern.

Option 4: 230,200,130,100,30,26230, 200, 130, 100, 30, 26
The differences between each consecutive term are: 200230=30200 - 230 = -30, 130200=70130 - 200 = -70, 100130=30100 - 130 = -30, 30100=7030 - 100 = -70, 2630=426 - 30 = -4.
These differences are not consistent, indicating no consistent pattern.

Therefore, the correct group that maintains the veracity as an arithmetic sequence is with a common difference of -4:

62, 58, 54, 50, 46, 42

Answer

62, 58, 54, 50, 46, 42
