Number Series is a form of numbers in a certain sequence, where some Numbers are mistakenly put into series of numbers and some numbers is missing in that series, We need to observe first and find the accurate number to that series of Numbers.

Here we have provided some Examples:

B. 605

c. 655

D. 625

A. 1071

The idea of proportion is that two ratios are like equal

If a : b = c : d. then we can write a : b ::c : d.

Here, a and d is called extremes and b and c is called mean terms.

The four Quantities like a, b, c, d are proportion, then we can express it as

a:b = c:d

then, a : b :: c : d (a x d) = (b x c)

Product of means = product of Extremes

If there is given three quantities like a, d, c of same like, then we can say it’s proportion are continued.

a : d = d : c

Here d is called mean term and a and c are called Extremes.

This type of series is based on ascending or descending sequence of numbers and each continuous number is obtained by multiplying or dividing the preceding number with static number.
