Explanation

The pattern is +5, +10, +5, +10, +5, +10. 3+5=8, 8+10=18, 18+5=23, 23+10=33, 33+5=38, 38+10=48.

AI explanation

The series is formed by alternating the operations of adding 5 and adding 10. Adding 5 to 3 gives 8, adding 10 to 8 gives 18, adding 5 to 18 gives 23, and adding 10 to 23 gives 33. To find the missing term, we add 5 to 33, which yields 38, and adding 10 to 38 correctly gives the final term of 48.
