Answer:
457
Step-by-step explanation:
The general term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
where a1 is the first term (-26), and d is the common difference (7).
The 70th term of your sequence can be found by putting the numbers into this formula:
a70 = -26 +7(70 -1) = -26 +483
a70 = 457
The 70th term of the sequence is 457.
To solve this problem, we need to recognize that Harry's age is given as "n". We can use this value and the given information to write expressions representing each person's age.
For Example, Jo is 2 years older than Harry and Harry's age is represented by the variable n. This means that n (Harry's age) plus 2 would equal Jo's age. This can be represented by the expression: n +2.
Next, we know that Kate is twice as old as Jo, and Jo's age is represented by the expression n+2. This means that 2 times Jo's age would be equal to Kate's age, or Kate's age = 2(n+2) or 2n +4.
Therefore, your answer is that Jo's age is n + 2 and Kate's age is 2n + 4.
