Question

two terms of the number series of which the general term is 10- 3n

Answer 1

Answer:

An = 10 - 3n

Putting value of n,

Let n = 1 ,

Then,  

A1 = 10 - 3 *1

A1 = 7

For n = 2,  

A2 = 10 - 3 *2  

A2 = 10 - 6 = 4  

For n = 3 ,  

A3 = 10 - 3 * 3  

A3 = 10 - 9 = 1  

Now,

A2 - A1 = 4 - 7 = - 3 = d  

A3 - A2 = 1 - 4 = - 3 = d

Since, Difference is common.  

So, Common difference is same.  

Hence, The given sequence is in A. P.
