Dear All,
I have the follow problem with the combination of a few lists.
I shall outline the problem or what I am trying to do.
I know that to solve this problem requires a number of processes, but I am
not sure how to setup the coding to achieve my desired result.
Please could someone show me the coding for this problem.
The problem:-
1 - I have a list1 created from 24+(15*n1) All n1 are integers
1,2,3,4.....to a large number of integers.
2 - I want to divide the list1 by 24 and create another list2 with only the
integer results in list2.
Table[24 + 15*i, {i, 100}]/24 ... so that integer results in list2
= { 144, 264, 384, 504, 624, 744, 864, 984, 1104 }
3 - I have another list3 created from 12+(3*n2) All n2 are integers
1,2,3,4.....to a large number of integers.
4 - With list3 I want to find :-
(i) The integer number of n2 that either equates 12+(3*n2) = 144 or
the next FIRST available number in list2 that meets this equality.
then also (ii)The integer number(s) of n2 that equates 12+(3*n2) = 24+(15*n1) after the first equal value for say 6 repetitions.
then also (iii)The integer number(s) of n1 that equates 12+(3*n2) =
24+(15*n1) after the first equal value for say 6 repetitions.
The above example is quite simple, but I am hoping to setup the coding to
work with other integer values instead of 3 & 15 which will present more of
a challenge.
Any help or advice greatly appreciated.
Best regards,
Lea...
