Question

Write down the next term of the sequence 2 5 11 20 32...

Write down the 5th term in the sequence given by: T(n)= n²- 7

Solve 3 x ≤ 6

If the relative frequency of a train being on time is 0.4 how often could you expect the train to be on time over 20 days?

Answer 1

2,5,1,20,32,47


`T(5)=5^2-7=18`


`3x\leq6\\ x\leq2`


`0.4\cdot20=8`
