Sequence & Series Questions with Solutions Tips & Tricks
Quantitative Aptitude Sequence & Series topic is one the most engaging and intriguing concept in Bank, SSC and others Exam. Since candidate love solving puzzles based on sequence & series. Sequence & series are closely related concepts & possess immense importance.
Progression is of 3 types:
- Arithmetic Progression
- Geometric Progression
- Harmonic Progression
- Arithmetic Sequence
If anyone wish to find any term in the arithmetic sequence, the arithmetic sequence formula should help you to do so. The critical step is to be able to identify or extract known values from the problem that will eventually be substituted into the formula itself.
Let’s start by examining the essential parts of the formula
Formula for the Find nth Term in the Arithmetic Progression
The first term of an arithmetic sequence is equal to 6 and the common difference is equal to 3. Find a formula for the n th term and the value of the 50 th term
Solution to Problem 1:
- Use the value of the common difference d = 3 and the first term a1 = 6 in the formula for the n th term given above an = a1 + (n – 1 )d= 6 + 3 (n – 1)
= 3 n + 3
- The 50 th term is found by setting n = 50 in the above formula.
a50 = 3 (50) + 3 = 153
An arithmetic series is the sum of an arithmetic sequence. We find the sum by adding the first, a1 and last term, an, divide by 2 in order to get the mean of the two values and then multiply by the number of values, n:

Find the sum of the following arithmetic series 1,2,3…..99,100
We have a total of 100 values, hence n=100. Our first value is 1 and our last is 100. We put the values into our formula and get:
Geometric sequences and series Examples for Bank Exam
A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
Harmonic Progression Example with Solutions
A harmonic progression is a sequence of real numbers formed by taking the reciprocals of an arithmetic progression. Equivalently, it is a sequence of real numbers such that any term in the sequence is the harmonic mean of its two neighbors.
