First term =a; common difference = d; number of terms = n; n th term = tn = a+(n-+).d.
So, sum of 4th and 8th terms = a+(4-1).d + a+(8-1).d = 2a+10d =24 (given) .... ( i)
Sum of 6th and 10th terms = a+(6-1)d + a+(10-1)d = 2a + 14d = 44 ....( ii)
By ( ii) - ( i), 4d = 20, or, d =5.
So, putting d in ( i), 2a+ 50 = 24,
Or, 2a = - 26, or, a = -13.
So, the first 3 terms of the AP are: a, a+d, a+2d = -13,-8,-3 ( Ans)

Let the first terms of the two APs be a and b and the common difference of each be d. If number of terms = n and n th term is tn, then, tn = a+(n-1).d and b+(n-1)d.
So, difference between the 100th terms = [ a+(100-1).d] -[b +(100-1)d] = (a+99d) -(b+99d) = 100 (given), or, a- b = 100 ... ( i)
So, the difference between the 1000th terms =[a+(1000-1)d] - [b+(1000-1)d] = a - b =100 (Ans) [from ( i)].
Ans : 100
