Write out the first four terms of the following sequence D01

Write out the first four terms of the following sequence. D_0=19, d_m=d_m-1/100, m inequality 1 Write out the first four terms of the following sequence. A_1=120, a_n+1=1/a_n, n inequality 1

Solution

1) do = 19: dm = (dm-1)/100

do =19

d1 = do/100 = 0.19

d2 = d1/100 = 0.0019

d3 = d2/100 = 0.000019

2) a1 = 120 ; an+1 = 1/an

a1 = 120

a2 = 1/a1 = 1/120

a3 = 1/a2 = 120

a4 =1/a3 = 1/120
