Question

The common diff of two different ap are equal

Answer 1

Answer:

1

Step-by-step explanation:

Two APs have the same common difference. The first term of one AP is 2 and that of the other is 7. The difference between their 10  

th

 terms is the same as the difference between their 21  

st

 terms, which is the same as the difference between any two corresponding terms.

If true then enter 1 and if false then enter 0

ANSWER

Let a,d and a  

n

​  

 be the first term, common difference and n^{th} of first AP and A,d and A  

n

​  

 be the first term, common difference and n^{th} term of second AP respectively.  

Given a=2 and A=7 a  

10

​  

−A  

10

​  

=a+9d−(A+9d)=a−A=2−7=−5  

Difference between any two corresponding terms of these AP's is equal to difference between first terms of these AP's.  

⇒ given statement is true so answer is 1.
