Answer 1

Hey friend..!! here's your answer
_________________________

AP : 12 , 16 ,20 ,.........,96

a = 12
d = 4
an = 96
We need to find n (number of terms)

an = a + (n - 1)d
96 = 12 + (n - 1) 4
96 = 12 + 4n - 4
96 - 8 = 4n
4n = 88
n = 22

So that 22 two digits numbers divisble by 4

a=12
cd=4
Tn=96

Tn=a+(n-1)d
96=12+(n-1)4
96-12=4n-4
84=4n-4
88=4n
22=n
