Question

if 7÷3,a,2 are in ap , find the value of a

Answer 1

• Half of the sum of adjacent A.P is equal to the middle one.


$\frac{ \frac{7}{3} + 2}{2} = a$

$\frac{ \frac{7 + 6}{3} }{2} = a$

$\frac{ \frac{13}{3} }{2} = a$

13/6 = a

Answer 2

2b=a+c
ATQ
2a=7÷3+2
2a=(7+6)÷3
2a=13÷3
a=13÷6
A=13/6 is your answer enjoy
