you may think that my question is foolish but
I do not understand the example above why d=2 and q=2 ?
Arithmetic progression: 2, 4, 6, 8, 10,... d=2
Geometric progression: 2, 4, 8, 16, 32,... q=2
Hi, in answer to your question,
in arithmetic progression d stands for 'difference'
so you would add the value of d to the previous number in the sequence to find out the next one. that's why in
2, 4, 6, 8,.. d = 2 because it's going up by 2.
in geometric progression q, i think, stands for 'quotient'
it's similar to arithmetic progression, but instead of adding the value, you times the value of q to the previous number to find out the next number in the sequence.
therefore in the sequence: 2,4,8,16, 32 .. q = 2 because you are multiplying 2 each time
hope this helps
