Question

(ii) How many two digit numbers are divisible by 4?

Two digit numbers divisible by 4 are

12, 16, 20, 21, ......., 96

a = ; d = , tn = 96

tn = a + (n – 1) d ... Formula

 96 = + (n – 1)

= 12 + 4n – 4

 4n =  n =​

Answer 1

Answer:

Step-by-step explanation:

The 2 digit number divisible 4 are 4,8,16.....96

Here,

T1=4 , t2=8 , t3=16......tn=96

a=4 ; d=4 ; tn=96 ; n=?

Using tn=a+(n-1) d

96=4+(n-1)4

96-4= (n-1)4

92=(n-1) 4

92÷4= (n-1)

23= (n-1)

23+1=n

24=n

Therefore there are 24 two digit number divisible by 4
