Answer:
the sum of the first 6 terms =189
Step-by-step explanation:
the first 6 terms-
96,48,24,12,6,3
I found them easily by dividing 48 with random small numbers until I got 6 for the fifth term. So here I divided 48 by 2 which is = 24(3rd term), then divided 24 by 2 which is =12(4th term) and then again decide the answer by 2 and finally got 6 for the 5th term. So the ratio is 1/2. For the first term I did the opposite, multiply 48 by 2 which is = 96. And lastly find the sixth term and add them up which is = 189
I tried my best to explain it in simple terms, hope this helps:)
