Explicit formula is useful to find any term of the sequence, without knowing the previous term. The explicit formula for the arithmetic sequence is an = a + (n - 1)d, and any term can be computed by substituting the n value for the term.
be a geometric sequence with common quotient q. The n-th term of the sequence is given by a_n = a_1 x q^(n-1). How do you find the formula for an arithmetic sequence? Let a_1, a_2, ... be an arithmetic sequence with common difference r. The n-th term of the sequence ...
The arithmetic sequence formula can be also expressed as an explicit function: {eq}a(n) = a(1) + (n-1)d {/eq} where the nth term is represented by a(n), and the common difference is represented by d. Let's take the sequence: 3, 8, 13, 18, 23, ...,, we substitute the...
We give an explicit arithmetic formula for the Fourier coefficients of the Siegel-Eisenstein series Ek-L of degree two on the congruence subgroup TQ (N) with a square free odd level A", where k is the weight and x 1S a primitive Diiichlet character mod N. If the level N exceeds one...

To start, we will use an arbitrary function which we will call the zeroth approximation, and apply this operator continuously to determine a sequence of successive approximations that will converge to the fixed point. This method will be applicable for linear and nonlinear FFDEs involving various ...
