Find a[1] and d for the arithmetic sequence with the given terms.
a[20] = 13, and a[25] = 33
We have
a[25] – a[20] = 20.
There are 5 steps from a[20] to a[25], so we divide by 5 to get
d = 4.
Then we proceed as before:
a[1] + 19d = a[20]
a[1] + 19(4) = 13
a[1] = -63.
Once we know we have an arithmetic sequence, if we s... | {"url":"http://www.shmoop.com/sequences/arithmetic-sequence-exercises-26.html","timestamp":"2014-04-17T10:24:30Z","content_type":null,"content_length":"29581","record_id":"<urn:uuid:48c419b3-2c45-42a1-9345-39a69ce2fef9>","cc-path":"CC-MAIN-2014-15/segments/1398223211700.16/warc/CC-MAIN-20140423032011-00089-ip-10-147-4-... |

May 2009
i have a mixture which has 87% of x and 13 % of y , which cannot be seperated.
if i need to make a mixture with 99.5 % of x and 0.5 % of y, how much of x and y should i mix.
pls answer quickly.
