1. sai1234

let n=1 just check a1=2a1-1 u can find answer

2. amistre64

is the now term, twice the last term?

3. CaitlinH

i dont understand

4. amistre64

do you know how to generate a sequance of numbers?

5. CaitlinH

not really

6. amistre64

the terms of the sequence here are named: a1 a2 a3 a4 a5 right?

7. CaitlinH

ok

8. amistre64

and they have certain values: a1 =2 a2 =4 a3 =8 a4 =16 a5 =32 right?

9. CaitlinH

yea

10. amistre64

so we have to compare this to the rule given to see if it matches up; the first part of the rule asks; does a1=2

11. CaitlinH

ok how do i do that

12. amistre64

you look at the list and see if a1 is equal to 2 to start off with .....

13. CaitlinH

ok then what will i do

14. amistre64

then you will compare the rule that states how each new term is formed from the the one before it and see if that matches

15. amistre64

for example; when n=2, what does n-1 equal?

16. CaitlinH

17. amistre64

maybe, but we havent finished checking to see if it matches the rules .....
