Sequence Calculator
Top
A Sequence is a systematic list of objects. In mathematics these list can be numbers, algebraic expressions etc.

Sequence Calculator gives the series of numbers in order as per the given function for the given range of numbers.
eg : n2, 2n, (n+1) etc.

You can see a default function with its range given below. When you click on "Calculate", the calculator will give the series of numbers by solving the function with respect to the given range.

## Steps for Sequence Calculator

Step 1 :

Observe the given function and the range given in the problem.

Step 2 :

Solve the function for all the numbers for the range given and get the answers. Write the answers accordingly in the braces which gives you the answer in form of sequence.

## Problems on Sequence Calculator

1. ### $\sum_{1}^{4}$ (n2 + 1)

Step 1 :

Given function is $\sum_{1}^{4}$ (n2 + 1) and range is {1,2,3,4}

Step 2 :

For n = 1, (n2 + 1) = 12 + 1 = 2

For n = 2, (n2 + 1) = 22 + 1 = 5

For n = 3, (n2 + 1) = 32 + 1 = 10

For n = 4, (n2 + 1) = 42 + 1 = 17.

The sequence for $\sum_{1}^{4}$ (n2 + 1) = {2, 5, 10, 17}.

2. ### $\sum_{1}^{2}$ 4n2

Step 1 :

Given function is $\sum_{1}^{2}$ 4n2 and range is {1,2}

Step 2 :

For n = 1, 4n2 = 4 $\times$ 12  = 4

For n = 2, 4n2 = 4 $\times$ 22 = 16.

The sequence for $\sum_{1}^{2}$ 4n2 = {4,16}.
