Answer:
an = 10n - 5
Step-by-step explanation:
Write an explicit formula for a n the nth term of of the sequence 5,15,25
An explicit formula for the above question is;
an = a+ (n - 1)d
Where
a = First term
d = Common Difference
n = nth term
We are given the sequence below:
5,15,25
The first term a = 5
Common Difference = 15 - 5 = 10
To find the nth term = an
an = a+ (n - 1)d
an = 5 + (n - 1)10
an = 5 + 10n - 10
an = 10n - 5

Answer:
210
Step-by-step explanation:
We can get 10% of 300 by doing 300 / 10 which is 30. 70 / 10 is 7, so we need 7 lots of 10% to work out 70%. Therefore, 30 * 7 students said that their favourite colour was blue, which is 210.
