Question

in the following AP,s find the missing terms in the boxes:5,□,□,9.5​

Answer 1

Answer:

the correct order of A. P is 5, 6.5 ,8 ,9.5

Answer 2

Answer:

5,□,□,9.5

a=5 , n=4 , an = 9.5

an = a+(n-1)d

9.5= 5+(4-1)d

9.5= 5 + 3d

3d= 9.5-5

3d = 4.5

d=1.5

a2 = a + d

= 5+1.5=6.5

a3 = a2 + d

= 6.5+1.5 = 8
