The correct answer is option 1 i.e. 1112, 6736.

Given:  3, 5, 14, 50, 216, ?, ?    

Pattern:

3 × 1 + 2 = 5

5 × 2 + 4 = 14

14 × 3 + 8 = 50

50 × 4 + 16 = 216

The next numbers will be: 1112, 6736

216 × 5 + 32 = 1112

1112 × 6 + 64 = 6736

Hence, the correct answer is 1112, 6736.

The correct answer is option 2 i.e. - 6.

Given: 64, 64, 60, 42, ?

Pattern:

64 - (1³ - 1²) = 64

64 - (2³ - 2²) = 60

60 - (3³ - 3²) = 42

Thus, the next number will be:

42 - (4³ - 4²)= - 6

Hence, the correct answer is - 6.

The correct answer is option 1 i.e. 570.75

Given series: 96, 132, 186, 267, 388.5, ?

The logic used here is: 

96 = (× 1.5) - 12 = 132

132 = (× 1.5) - 12 = 186

186 = (× 1.5) - 12 = 267

267 = (× 1.5) - 12 = 388.5

388.5 = (× 1.5) - 12 = 570.75

The correct answer is Option 2 i.e. ONJB

KBFP, LEGS, MHHV, NKIY, ?

K + 1 = L, L + 1 = M, M + 1 = N, N + 1 = O

B + 3 = E , E + 3 = H, H + 3 = K, K + 3 = N

F + 1 = G, G + 1 = H, H + 1 = I, I + 1 = J

P + 3 = S , S + 3 = V, V + 3 = Y, Y + 3 = B

Hence, the correct answer is ONJB.

The correct answer is Option 2 i.e. TKQ.

Given series

KTW, NQU, QNS, ?, WHO

K + 3 = N, N + 3 = Q, Q + 3 = T, T + 3 = W

T - 3 = Q, Q - 3 = N, N - 3 = K, K - 3 = H

W - 2 = U, U - 2 = S, S - 2 = Q, Q - 2 = O

Hence, the correct answer is TKQ.

The correct answer is option 2 i.e. B

The logic which follows here is:

The shaded square is increasing by 1 in each figure.

The slant lines are rotating in a clockwise direction at the corners of the images.

The letters inside the triangle follow the logic of +2.

D, D + 2 = F, F + 2 = H, H + 2 = J

Hence, the correct answer is B.

The correct answer is option 1 i.e. A

The logic which follows here is:

The triangle is inside the figure.

In each step, the side of the figure is increasing by 1.

Hence, in the next image, Triangle will be inside 6 sided figure i.e. Hexagon.

Hence, the correct answer is A.

The correct answer is option 2 i.e. B

The logic which follows here is:

The shaded square is increasing by 1 in each figure.

The slant lines are rotating in a clockwise direction in the corners of the images.

The letters follow a logic of × 2.

2 (B), 2 × 2 = D (4), 4 × 2 = H (8), 8 × 2 = P (16)

Hence, the correct answer is B.

The correct answer is option 4 i.e. bjdhadh.

Given series: a _ d e _ h a b _ e j _ _ b _ e j _

Option 4: bjdhadh

a _ d e _ h a b _ e j _ _ b _ e j _

a b d e j h a b d e j h a b d e j h 

This makes a sequence of a b d e j h / a b d e j h / a b d e j h 

Hence, the correct answer is bjdhadh.

The correct answer is Option 3 i.e. Inert Gas.

Chlorine is an element of the Halogen group.

Neon is an element of the Inert Gas group.
