Answer:
x = 5.9
Step-by-step explanation:
Step 1: Write equation
14 = 31.7 - 3x
Step 2: Solve for <em>x</em>
<u>Subtract 31.7 on both sides:</u> -17.7 = -3x
<u>Divide both sides by -3:</u> x = 5.9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
14 = 31.7 - 3(5.9)
14 = 31.7 - 17.7
14 = 14

Answer: the first term of the series is 128
Step-by-step explanation:
In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = a(1 - r^n)/(1 - r)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
r = 1/4 = 0.25
n = 4
S4 = 170
Therefore, the expression for the sum of the 4 terms, S4 is
170 = a(1 - 0.25^4)/(1 - 0.25)
170 = a(1 - 0.00390625)/(1 - 0.25)
170 = a(0.99609375)/(0.75)
170 = 1.328125a
a = 170/1.328125
a = 128
Answer:
r
