Write the sequence of the following explicit formula:
1. sn = (-4)n , 1 <_ n
2. tn = 92 -5n, 1<_n <_5
1) Here "S_n=(-4)n" , "n\\geq1"
Therefore "S_1=(-4)"
"S_2=(-8)"
"S_3=(-12)"
.
.
"S_n=(-4)n"
"\\therefore" In explicit form
{ "(-4),(-8),(-12),.....,(-4)n" }
2)Here "t_n=92-5n,1\\leq n\\leq5"
Therefore, "t_1=92-5.1=87"
"t_2=92-5.2=82"
"t_3=92-5.3=77"
"t_4=92-5.4=72"
"t_5=92-5.5=67"
"\\therefore" In explicit form {"87,82,77,72,67" }
