Question

Ap progression
5,?,?,9 1/2 find missing terms

Answer 1

Answer:

Missing terms are 13/2 and 8

Step-by-step explanation:

For the arithmetic progression....

a=5 and a4=19 1/2

As we know that,for an AP,

an=a+(n-1)d

Therefore,by putting the values here,

a4=a+(4-1)d

19 1/2 =5+3d

3d =19 1/2-5

3d = 9 1/2

d = 3/2

a2=a+(2-1)d

a2=5+3/2

a2= 13/2

a3=a+(3-1)d

a3=5+2×3/2

a3=8

Therefore,the missing terms are 13/2 and 8 respectively...
