# Choose the correct one From the Series Given Below

**A. **4, 7, 12, 19, 28, ____

- 30
- 36
- 39
- 49

**B. **b 3 P, c 6 R, d 12 T, e 24 V, ____

- f 46 X
- g 48 X
- g 48 V
- f 48 X

**A. Answer: (3) 39**

**Explanation:-**

4 + 3 = 7, 7 + 5 = 12, 12 + 7 = 19, 19 + 9 = 28, 28 + 11= 39.

Hence, the answer is (3) 39.

**B. Answer : (4) f 48 X**

**Explanation:- **

b + 1 = c, 3 x 2 = 6 and P + 2 = R,

c + 1 = d, 6 x 2 = 12 and R + 2 = T,

d + 1 = e, 12 x 2 =24 and T + 2 = V,

Similarly,

e + 1 = f, 24 x 2 = 48 and V + 2 = X

Hence, the answer is (4) f 48 X.
