Answer 1

Answer:

The middle term of an A.P is 125.  

Step-by-step explanation:

Given :  

A.P. 213, 205, 197, ...., 37.

Then ,  

First term , a = 213 , last term ,l = 37  

By using the formula , Middle term of an A.P = ½ (a + l)

Middle term of an A.P = ½ (213 + 37)

Middle term of an A.P  = ½ × 250

Middle term of an A.P = 125

Hence, the middle term of an A.P is 125.

Answer 2

Answer: 125

 

Step-by-step explanation:

Given A.P. : 213, 205, 197.. 37.

Thus ,  

a = 213 ( first term )

l = 37  ( last term )

To find the middle term of given A.P,

we'll use the formula: ½ (a + l)

Middle term of given A.P = ½ (213 + 37)

= ½ × 250

= 125

Thus, the middle term of given A.P is 125.
