Question

IF you are given he following sequence:  1, 4, 7, 10, 13... in what number will the 10th "4" be found

Answer 1

1, 4, 7, 10, 13, ...

you are adding 3 to each number to get the next number

you have to add 3 ten times (30) to get another 4; 4+30=34

3+4=7, 7+3=10,10+3=13, 13+3=16, and so on until you come to 34

the next number with 4 in the one's place is 64 (34+30)

then comes 94, 124, 154, 184, 214, 244, and finally 274

4, 34, 64, 94, 124, 154, 184, 214, 244, 274 (274 has the 10th 4 in the one's place)

by the way, 274 happens to be the 92nd number in the sequence
