Step-by-step explanation:
Given sequence is -5, -1, -5, -25,..
In any arithmetic series nth term is given by a + (n-1)d
where a is the first term
and d is the common difference.
d = nth term - (n-1)th term
For the given series
a = -5
lets take nth term as 2nd term and 1st term as (n-1)th term
d = -1-(-5)= -1+5 = 84
n th term = a + (n-1)d
using the formula for nth term
4th term = 5 + (4-1)8 = 29
Quotient 98 and remainder 632 i think
<span>w - amount of wheat purchased
r - amount of rye purchased
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour</span>
9.4-0.1 = 9.3
The range is highest minus lowest
