The 1st term is -67
Step-by-step explanation:
I. When Sn = (
)
If Sn = 124, n = 8 and = 98
124 = 8/2(a + 98)
124 = 4(a + 98)
124 = 4a + 392

Answer:
<h3>p = 131.25</h3>Step-by-step explanation:
The variation p varies directly with T is written as
p = kT
where k is the constant of proportionality
To find p when T =500 we must first find the formula for the variation
That's
when p = 105 and T = 400
105 = 400k
Divide both sides by 400
<h3>So the formula for the variation is
<h2>when
T = 500
Substitute it into the above formula
That's
Simplify
The final answer is
<h3>p = 131.25</h3>Hope this helps you
