Position of first number in array greater than a given number
Hi all,
I am new to the forum and have searched for the answer to my formula query. Appologies if I have missed an existing solution, a link would be much appreciated if it already exists. My knowledge of referencing and look up formulas is very limited. here is what I thought was a simple function problem: In a one column vertical array of numbers I wish to find two seperate things. Firstly the position in the array (from the top down) of the first occurrence of a number greater than a number in an adjacent cell. Secondly, the position in the array (from the top down) of the last occurrence of a number greater than another number in an adjacent cell. eg: Array: 6, 9, 3, 4, 2, 8, 8, 2, 7, 5, 6, 1, 4, 3 Adjacent cell contains 7 (first query) Another adjacent cell contains 5 (Second query) The answers I am trying to write a formula to obtain are Query one answer is 2, ie position 2 in the array is the first entry higher than 7. Query two answer is 11, ie the 11th entry in the array is the last one greater than 5. I suspect the two formulas required are similar uses of multiple referencing functions. What my sheet goes onto use from the above is simply "Is the last occurrence greater than 5 after the first occurance of greater than 7?" True or False would suffice if it is an easier formula to put together, but I suspect it is simpler to do it in stages with the two seperate queries and compare the answers. Any pointers or formulas to implement the above would be very gratefully received , I have mused over it for weeks now and it is certainly beyond me. Thanks Krapdad (yes, krap at parenting and also krap at Excel formulas!) |
