Heya !!
A3 = 8
A + 2D = 8 --------(1)
And,
A7 = 24
A + 6D = 64 --------(2)
From equation (1) we get,
A + 2D = 8
A = ( 8 - 2D ) ---------(3)
Putting the value of A in equation (2)
A + 6D = 24
8 - 2D + 6D = 24
4D = 24 - 8
D = 16/4 = 4
Putting the Value of D in equation (3)
A = 8-2D = 8 - 2 × 4
A = 8-8 = 0
First term ( A ) = 0
And,
Common difference ( D ) = 4
Therefore,
A10 = A + 9D = 0 + 9 × 4
A10 = 36.
