Sequence & Series Questions with Solutions Tips & Tricks

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
Problem 1:
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:
