Question

Give (a) the first four terms of the sequence for which a_n is given and (b) the first four terms of the infinite series associated with the sequence.

Give (a) the first four terms of the sequence for which a n is given and (b) the first four terms of the infinite series associated with the sequence. a n = (- 2/3)n, n = 1, 2, 3,... a 1 = a 2 = a 3 = a 4 = (Type integers or simplified fractions.) The first four terms of the infinite series associated with the given sequence are and (Type integers or simplified fractions.)

Explanation / Answer

(a) a1= -2/3 a2= 4/9 a3= -8/27 a4= 16/81

(b) for infinite series n will be go to infinity,there will be no effect on first four terms,hence they will remain same
