Q.191Medium
Six people sit around a circular table: F, G, H, I, J, K. G sits 2 seats to the right of F. H sits opposite to J. I is not adjacent to G. K sits to the left of F. Who sits between I and J (clockwise from I)?
Answer: C
In a circular arrangement with 6 seats: If K is to the left of F and G is 2 seats to the right of F, we get a relative positioning. H opposite to J means they are 3 seats apart. With I not adjacent to G, the arrangement works out as: F, G (2 seats right), then H, J (opposite), and I, K positioned accordingly. The person between I and J clockwise is H.
Q.192Medium
In a series: 2, 6, 12, 20, 30, 42, ?. What is the next number?
Answer: A
The differences are: 6-2=4, 12-6=6, 20-12=8, 30-20=10, 42-30=12. The differences increase by 2 each time. Next difference should be 14, so 42+14=56.

In a series: 5, 11, 23, 47, ?, what is the next number?
Count of vowels: CAT(A)=1, DOG(O)=1, ELEPHANT(E,A)=2, ZEBRA(E,A)=2. Actually, ZEBRA has E and A = 2 vowels. Wait - checking again: Z-E-B-R-A has E,A = 2. Let me reconsider: if counting syllables or letters with curves: Z(0),E(0),B(1),R(0),A(0)=1? Pattern might be unique letters or vowel positions. ZEBRA = 5 letters.
Q.197Medium
A is taller than B. B is taller than C. C is as tall as D. D is shorter than E. Who is the shortest?
