Mark the group that maintains the veracity.
To solve this problem, we'll follow these steps:
Now, let's analyze each choice:
Option 1:
The differences between each consecutive term are: , , , , .
These differences are not consistent, indicating no consistent pattern. Thus, this is not an arithmetic sequence.
Option 2:
The differences between each consecutive term are: , , , , .
These differences are all consistent, indicating an arithmetic sequence with a common difference of .
Option 3:
The differences between each consecutive term are: , , , , .
These differences are not consistent, indicating no consistent pattern.
Option 4:
The differences between each consecutive term are: , , , , .
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
62, 58, 54, 50, 46, 42
Is there a term-to-term rule for the sequence below?
18 , 22 , 26 , 30
A sequence maintains veracity when it follows a consistent mathematical rule throughout. For arithmetic sequences, this means having the same difference between every pair of consecutive terms.
Calculate each difference: term₂ - term₁, term₃ - term₂, etc. If all differences equal the same number (like -4, -4, -4), you have an arithmetic sequence!
Absolutely! A negative common difference means the sequence is decreasing. For example, 62, 58, 54, 50 has a common difference of -4.
That indicates no consistent pattern. True arithmetic sequences must have identical differences - all positive, all negative, or all zero.
Option 2 (62, 58, 54, 50, 46, 42) is the only sequence where every difference equals -4. The other options have varying differences, breaking the arithmetic sequence pattern.
