The nth term of a sequence is given by an’ + bn where a and b are integers. The 2nd term of the sequence is 2
The 4th term of the sequence is 20
a) Find the 6th term of the sequence.
(4)
Here are the first five terms of a different quadratic sequence.
2 6 12 20 30
b) Find an expression, in terms of n, for the nth term of this sequence.
(2)
Total marks: 6

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to

13/28 is the answer
