Answer: The answer is 5, 10, 20, 40 and 80.
Step-by-step explanation: We are to write the first five terms of a sequence, along with the explicit and recursive formula for the general term of the sequence.
Let the first five terms of a sequence be 5, 10, 20, 40 and 80. These terms are taken from a geometric sequence with first term and common ratio
Therefore, we have
Therefore, the recursive formula is
And explicit formula is
Answer:
Let M represents the Male and F represents the Female.
As per the statement:
There are 6 times as many males as females on the maths course at university.
⇒ M = 6F
Total number of person on the maths course = M + F = 6F+ F = 7F
we have to find the fraction of the course are male;
Substitute the given values we have;
therefore, the fraction of the course are male is,
