Find the sum of the first 3 terms of a geometric sequence with a=96 and r=1/4 the sum is____.
1 answer:
For Geometric sequence, the next term is multiplied by the common ratio.
Common ratio, r = 1/4
1st term, a = 96
2nd term = ar = 96*1/4 = 24
3rd term = ar² = 96*(1/4)*(1/4) = 6
Sum of the first three terms = 96 + 24 + 6 = 126

Answer:
$81
Step-by-step explanation:
9/2 = 4.5
4.5 x 18 = 81
Y = 5x + b
Plug in the point
35 = 5(-8) + b
35 = -40 + b, b = 75
Solution: y = 5x + 75
40% of 500 = 200
10% of 500 = 50 so just times it by 4
It’s B I hope this helps :)
