Answer:
is proved for the sum of pth, qth and rth terms of an arithmetic progression are a, b,and c respectively.
Step-by-step explanation:
Given that the sum of pth, qth and rth terms of an arithmetic progression are a, b and c respectively.
First term of given arithmetic progression is A
and common difference is D
ie., and common difference=D
The nth term can be written as
pth term of given arithmetic progression is a
qth term of given arithmetic progression is b
and
rth term of given arithmetic progression is c
We have to prove that
Now to prove LHS=RHS
Now take LHS
ie.,
Therefore
ie.,
Hence proved
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable
Exact Form:
x = - 25/8
Decimal Form:
x = -3.125
Mixed Number Form:
x = - 3/1/8
Step-by-step explanation:
To factor a difference of squares, the following steps are undertaken: Check if the terms have the greatest common factor (GCF) and factor it out. Remember to include the GCF in your final answer. Determine the numbers that will produce the same results and apply the formula: a2– b2 = (a + b) (a – b) or (a – b) (a + b)
