$$1\frac{1}{7}, 3\frac{6}{7}, 9\frac{1}{7}, 17\frac{6}{7}, ...........$$

Video Solution

Solution

$$1\ \frac{\ 1}{7}=\ \frac{\ 8}{7}=\ \frac{\ 2^3}{7}.$$

$$3\frac{\ 6}{7}=\ \frac{\ 27}{7}=\ \frac{\ 3^3}{7}.$$

$$9\frac{\ 1}{7}=\ \frac{\ 64}{7}=\ \frac{\ 4^3}{7}.$$

$$\ 17\frac{\ 6}{7}=\ \frac{\ 125}{7}=\ \frac{\ 5^3}{7}.$$

$$\ 30\frac{\ 6}{7}=\ \frac{\ 216}{7}=\ \frac{\ 6^3}{7}.$$

So, B is correct choice.

AP Police SI Mains 2019 Arithmetic and Reasoning - Question 133

1, 4, 10, 20, .........

Video Solution

Solution

f(n)$$=\frac{n\left(n+1\right)\left(n+2\right)}{6}.$$

So,$$f(1)=1$$

$$f(2)=4$$

$$f(3)=10$$

$$f(4)=20$$

$$f(5)=35$$

So,B is correct choice.

AP Police SI Mains 2019 Arithmetic and Reasoning - Question 134

ABC, BDF, CFI, DHL, .......

Video Solution

Solution

$$ABC\longrightarrow\ $$ has no gap between letters.

$$BDF\longrightarrow\ $$ has one letter gap.

$$CFI\longrightarrow\ $$ has two letters gap between them.

$$DHL\longrightarrow\ $$ has three letters gap between them.

So, next word in the series is EJO(each letter has 4 gaps between them).

A is correct choice.

AP Police SI Mains 2019 Arithmetic and Reasoning - Question 135

B, C, E, G, .......

Video Solution

Solution

next letter of B is C.

After one letter of C is E.

So,4 letter after G is K.

So,C is correct choice.

AP Police SI Mains 2019 Arithmetic and Reasoning - Question 136

AZ, CW, FR, JK, .......

Video Solution

Solution

Using conversion table,

$$AZ=1+26=27.$$

$$CW=3+23=26.$$

$$FR=6+18=24.$$

$$JK=10+11=21.$$

So,27,26,24,21 are in difference of 1,2,3 respectively.

So,next number should be 17.

$$OB=15+2=17.$$

So, B is correct choice.
