1.	AP:-11, -7, -3,...., 45IFind the middle term of the AP: -11, -7, -3,,. 45.
Answer» For AP - 11, - 7, - 3,........, 45a= -11 a2= -7a3= -3d= a2- a= -7+11= 4also = a+ (n-1)d45 = -11+(n-1)445 = -11 + 4n-445 = 4n-1545+15 = 4n60 = 4nn = 15 So, It means the Given AP have odd no. of terms so, the middle term is the 8th termapplying the formula as:-= -11 + (8-1)4=-11 +28=17 So the middle term is 17

Answer»

For AP - 11, - 7, - 3,........, 45a= -11 a2= -7a3= -3d= a2- a= -7+11= 4also = a+ (n-1)d45 = -11+(n-1)445 = -11 + 4n-445 = 4n-1545+15 = 4n60 = 4nn = 15

So, It means the Given AP have odd no. of terms so, the middle term is the 8th termapplying the formula as:-= -11 + (8-1)4=-11 +28=17 So the middle term is 17
