A sequence has a first term of 24 and every other term is one half of the previous term.
Find a recursive formula that defines this sequence.
The answer of this question is:
an=an1*1/2
Somebody can help me and let me know why is 1/2 on the formula? please please!!!

Umm, because it was given:
"every other term is one half of the previous term"
