42 is the next number in this sequence. This number sequence is  adding the next prime number to the last number. So 1 + 2 = 3. Then  3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 â¦ + 11 = 29.  The next prime number after 11 is 13, so 29 + 13 = 42.   The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23).his number sequence is  adding the next prime number to the last number.

Formal training for electricians combines an apprenticeship and classroom work. Electrician apprentices work full time and take about 144 clock hours of classroom courses, per year, for three to five years. Alternatively, some students opt to do the classroom work first by taking courses at a technical school or community college.
