Sum of 1st 2 terms, A2 = 2 + 4 = 6
Sum of 1st 3 terms, A3 = 2 + 4 + 6 = 12
Sum of 1st 4 terms A4 = 2 + 4 + 6 + 12 = 20
you can create a formula for the sum of the 1st n terms of this sequence
Sum of 1st n terms of this sequence = n2 + n
so the sum of the first 48 terms of the sequence is 482 + 48 = 2352
A quadratic sequence is when the difference between two terms changes each step. To find the formula for a quadratic sequence, one must first find the difference between the consecutive terms. Then a second difference must be found by finding the difference between the first consecutive differences.
well the first four terms are n=1,2,3 and 4 so just substitute those numbers into k=3n so k= 3,6,9,12
i need it nowww
you must find the pattern of the sequence in order to find the next 50 terms using that pattern and the first part of the sequence given
Find the sum of the first 11 terms in the sequence 3 7 11
We need the common difference to accurately get the first term and then use it to find the sum of the first 20 terms.

because you add the first 2 terms and the next tern was the the sum of the first 2 terms.

The Nth partial sum is the sum of the first n terms in an infinite series.

It seems that you can't express that integral in terms of a finite number of commonly used functions. In the Wolfram Alpha site (input: "integral cos sin x"), you can find the first few terms of an infinite series expansion.
