Question 4
1 / -0

Find next term
$$462,552,650,756,870,992,?$$

A
$$1040$$

B
$$1122$$

C
$$1132$$

find: $$3, 6, 21, 28, 55, 66, ?, 120$$

A
$$103$$

B
$$104$$

C
$$108$$

D
$$106$$

E
$$105$$

Solution

$$3\times 1=3$$
$$3\times 2=14$$
$$7\times 3=21$$
$$7\times 4=28$$
$$11\times 5=55$$
$$11\times 6=66$$

So, the next number is 15.
$$\Rightarrow 15\times 7=105$$
$$15\times 8=120$$

The series:- $$3,6,21,28,55,66,105,120$$
Question 6
1 / -0

Determine the next term $$20, 24, 33, 49, 74, 110, ?$$

A
$$133$$

B
$$147$$

C
$$159$$

D
$$163$$

E
$$171$$

Solution

$$20,24,33,49,74,110,...$$

Let the number be $$x$$

difference $$24-20=4,33-24=9,49-33=16,74-49=25,110-74=36,x-110=49$$

$$\implies24-20=2^2, 33-24= 3^2, 49-33= 4^2, \,\, 74-49= 5^2\,\, 110-74=6^2,\,\,\, x-110= 7^2$$

So, $$110+49=159$$

ANSWER IS C

$$21.875$$

D
$$17.5$$

E
$$90$$

Solution

$$120,15,105,17.5,87.5,.....$$
$$\dfrac{120}{8}=15$$
$$15\times 7=105$$
$$\dfrac{105}{6}=17.5$$
$$17.5\times 5=87.5$$
$$\dfrac{87.5}{4}=21.875$$
ANSWER IS C
