2022/075) Given the two number patterns: 1,5,9,13,17... and 1,4,7,10,13... How do I find their 13th common number?

 in the 2 patterns the 1st number is same.

now 1st pattern has common diffrerence 4 and 2nd one 3

the minimum common number difference shall be LCM(4,3) or 12

so 13th common number shall be 1 * 12 * (13–1) = 145
