Answer» 24is the correct answer 24 is the correct answer. two digit no are 10 to 99a= 12, d=4, an=96let n be the terma+(n-1)d=9612+(n-1)(4)=964n-4=96-12=844n= 84+4=88n= 88/4=22there are 22 term between 10 to 99 (two digit number) divisible by 4 n=22 is the best answer formula an=a+(n-1)d 12,16,20.......96. n=? a=4 an=96 d=4 96=4+(n-1)4. 96=4+4n-4. 96=4n. n=96/4. n=24 24 is the correct answer 25 two digit no. are divide by 4 highest 2 digit no. = 98 a = 4 d =4 as A. P. = 4 ,8 ,12 ,16 .........96 as an = a + (n-1)d96=4 + (n-1)496=4+4n-496=4nn=96÷4n=24 |
