We should not accept multiple of 3 value;
5 * 2 = 10,
5 * 4 = 20,
5 * 5 = 25,
5 * 7 = 35,
5 * 8 = 40,
5 * 10 =50,
5 * 11 = 55,
5 * 13 = 65,
5 * 14 = 70.
5 * 2 = 10,
5 * 4 = 20,
5 * 5 = 25,
5 * 7 = 35,
5 * 8 = 40,

10 20 - 10 Difference. And 20-25- 5 Difference.
25-35 - 10 Difference. And 35-40 - 5 Difference.
40-50 -10 Difference And 50-55 - 5 Difference.
55+10= 65 and 65+5= 70 => Ans
So, Option E 65 70.
25-35 - 10 Difference. And 35-40 - 5 Difference.
40-50 -10 Difference And 50-55 - 5 Difference.
55+10= 65 and 65+5= 70 => Ans

10 20 25 35 40 50 55.
Make it as set of 3
10 + 25 = 35, 35 + 20 = 55, 55 + 15 = 70.
20 + 20 = 40, 40 + 20 = 60, 60 + 20 = 80.
25 + 25 = 50, 50 + 25 = 75, 75 + 25 = 100.
