Answer 2

Answer:

17.5 will be the correct answer for the series of 2:5::7: ?

Step-by-step explanation:

Given,

2:5::7: ?

STEP 1:

First of all, we have to analyse the sequence and understand

STEP 2:

2/5 =  7/ X

STEP 3 :

X = 7x5 / 2 ( through cross multiplication method)

STEP 4:

X = 17.5

The simple number system is given in which have to convert the ratio into numbers by division and then similarly we have to do cross multiplication and we will get the next term or missing number, we have to divide two/ 2 by five/ 5 equal to seven/7 divide by X the missing term

Hence, 2 : 5 : : 7 : 17.5

Will be the correct sequence of numbers in the given number system.

2/5= 7/17.5
