The first term of a sequence is 29, and the fourth term is 50.

What are the second and third terms?

36 and 43
36 and 42
37 and 42
37 and 43

The common difference between consecutive terms is:

(50 - 29) รท (4 - 1) = 7.67

Since this is not a whole number, we know that the sequence is not arithmetic. However, we can still use this information to find the second and third terms. We can round the common difference to 8 and use it to find the next two terms:

Second term = first term + common difference
Second term = 29 + 8
Second term = 37

Third term = second term + common difference
Third term = 37 + 8
Third term = 45

Therefore, the second and third terms are 37 and 45. The closest answer choice is (C) 37 and 42, but this is not correct.
