If the pth term of an A.P. is q and the qth term is p. Prove that its nth term is (p+q-n).
Answers
pth term of an AP = q
qth term = p
Prove:nth term of A.P. is (p+q-n).
Proof:We know that,
nth term of an AP (an) = a + (n - 1)d
Hence,
⟹ a + (p - 1)d = q
⟹ a + pd - d = q
⟹ a = q - pd + d -- equation (1)
Similarly,
⟹ a + (q - 1)d = p
Substitute the value of a from equation (1).
⟹ q - pd + d + qd - d = p
⟹ qd - pd = p - q
⟹ - d(p - q) = p - q
⟹ - d = 1
⟹ d = - 1
Substitute the value of d in equation (1).
⟹ a = q - p( - 1) + ( - 1)
⟹ a = q + p - 1
Now,
an = q + p - 1 + (n - 1)( - 1)
⟹ an = q + p - 1 - n + 1
⟹ an = p + q - n
Hence, Proved.
I hope it will help you.
Regards.
Step-by-step explanation:
ANSWER
pth term = q
a+(p−1)d=q
qth term = p
a+(q−1)d=p
Solving these equations, we get,
d=−1
a=(p+q−1)
Thus,
nth term = a+(n−1)d=(p+q−1)+(n−1)×(−1)=(p+q−n)

The real numbers are 7, 8, and 9.
We are given two statements:
All real numbers are less than or equal to 9.All real numbers are greater than or equal to 7.We have to use these two statements, form an inequality for the real number and find the real numbers.
What is inequality?Inequality is a relation that makes a non-equal comparison between two mathematical expressions.
There are five types of inequality:
[tex]Less~~than~ = ~ < \\Greater~~than~=~ > \\Less~~than~~or~~equal~~to~=~\le\\Greater~~than~~or~~equal~~to~=~\ge[/tex]
Let the real number be x.
Now using the two given statements we have,
[tex]x\le9\\x\ge7[/tex]
If we combine these two equations we get,
[tex]7\le x \le 9[/tex]
Thus we can say that the real numbers are 7, 8, and 9.
