Is second term of a geometric series is 48 and it's fifth term is 6 then find the sum of the first 6 terms.​
AlekseyPX

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:)

Dr Wellbee advised his patients to drink 8 eight-ounce glasses of water everyday for every 50 pounds of weight. Kelby drank 168
BlackZzzverrR [31]
Kelby drank 168 glasses of water per week
i.e 24 glasses per day

Since 8  eight-ounce glass of water is for every 50 pounds.
1 eight-ounce glass is for = 50/8 pounds
and 24 glasses of water is for = 50*24/8
= 150pounds

So kelby probably weighs 150 pounds
