Q12.the calculation will be ------>> 3+1.5=4.5
4.5+2.5=7
4+2=6(adding 0.5 with 1.5, that is equal to 2)
6+2.5=8.5
5+2.5=7.5(adding 0.5 with 2 we get 2.5)
7.5+2.5=10

6. 18,6,24,4,30,10,12,2,6,?

first take d alternate nos.
first part-18,24,30,12,6
if u can see its multiple of 6
so 6*3=18
6*4=24
6*5=30
6*2=12
6*1=6

second term- 6,4,10,2, ?
these are multiple of 2
2*3=6
2*2=4
2*5=10
2*1=2

so in multiples of 2 evry no is multiplied sequencly but it is not multiplied by 4
therefore 2*4=8

Q1. (31 + 30 )/2 = 30.5 (No difference at all) so 30.5,31,30
Now (67+70)/2 = 68.5-67.2 = 1.3 difference
So Now there should be 2.6 difference, as difference of 0,1.3, 2.6 etc.
