Answer:

C.

1. an= 5n+6

  • a1 = 5(1)+6
  • = 5+6
  • = 11
  • a2 = 5(2)+6
  • = 10+6
  • = 16
  • a3 = 5(3)+6
  • = 15+6
  • = 21
  • a4 = 5(4)+6
  • = 20+6
  • = 26
  • a5 = 5(5)+6
  • = 25+6
  • = 31

2. an = 12-3n

  • a1 = 12-3(1)
  • = 12-3
  • = 9
  • a2 = 12-3(2)
  • = 12-6
  • = 6
  • a3 = 12-3(3)
  • = 12-9
  • = 3
  • a4 = 12-3(4)
  • = 12-12
  • = 0
  • a5 = 12-3(5)
  • = 12-15
  • = -3

3. an = 10n-15

  • a1 = 10(1)-15
  • = 10-15
  • = -5
  • a2 = 10(2)-15
  • = 20-15
  • = 5
  • a3 = 10(3)-15
  • = 30-15
  • = 15
  • a4 = 10(4)-15
  • = 40-15
  • = 25
  • a5 = 10(5)-15
  • = 50-15
  • = 35

D.

1. an = a+(n-1)d

  • a26 = 2+(26-1)2
  • = 2+(25)2
  • = 2+50
  • = 52

2. an = -11n+110

  • a12 = -11(12)+110
  • = -132+110
  • = -22

3. an = a+(n-1)d

  • a66 = 13+(66-1)3
  • = 13+(65)3
  • = 13+195
  • = 208
