Question

Sum of first five terms of an ap is 45. what is the third term

Answer 1

Given:-

Sum of Arithmetic Progression is =45

let the A.P be,

a-2d,a-d,a,a+d,a+2d

Solution:-

adding the A.P's we get,

=> a-2d+a-d+a+a+d+a+2d=45

=> 5a=45

=> a= 45/5

=> a=9

Therefore the Third term 'a' in the sequence is, 9

The third term is 9
