Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷ = 3 ÷ = 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = and r = 10 , thus
=
= ×
= 3 × ×
= 3 ×
Thus
= 3 → C
Answer:
87.8
Step-by-step explanation:
0.15(92+86+88+90) + 0.2(84) +
0.2(88)
= 0.15(356) + 16.8 + 17.6
= 87.8
#1 = -2 over -3. #2= y - (3.8)= 2.6(x-5.1)
