Question

if 3=18, 4=32, 5=50, 6=72,7=98 then,10=?

Answer 1

10 = 200 because if u will divide  bigger value with the small number there is always a gap of 2.
EG = 18/ 3= 6
and 32/4 8
GAP OF TWO.. 
LIKE THAT........ for 5 =10
6= 12
7= 14 
8= 16
9= 18 and 10= 20
or  u have to multiply the smaller number by 2 and then the answer with bigger value............

Answer 2

10=200 is the missing number in the series.

3=18, 4=32, 5=50, 6=72, 7=98 then 10=200

Step-by-step explanation:

Given:

3=18, 4=32, 5=50, 6=72,7=98 then 10=?      

To find:

The missing sequence 10=?    

Solution:

• This is a sequence that relates to the specific numbers or alphabet
• We need to analyze the given sequence for the search of series.
• Series was related to numbers. This is a numeric sequence, where numbers are related to the number in order.
• In the given pattern is natural numbers from(3,4,5,6,7,8,9,10) gets multiplied with even numbers starting from (6,8,10,12,14,16,18,20) orderly.

3=18, 4=32, 5=50, 6=72,7=98 then 10=?

3=18⇔3×6

4=32⇔ 4×8

5=50⇔ 5×10

6=72⇔ 6×12

7=98⇔ 7×14

8=128⇔ 8×16

9=162⇔9×18

The missing number is given by 10=200 ⇔10×20

The multiplication of natural numbers with even numbers (3×6, 4×8, 5×10, 6×12, 7×14, 8×16, 9×18, 10×20)

Hence,

The missing number 10=200

3=18, 4=32, 5=50, 6=72,7=98 then 10=200
