A sequence of numbers is defined by the following rule: each term after the first two terms is the sum of the previous two terms. If the first term is 3 and the second term is 5, what is the value of the eighth term in the sequence?
This is a Fibonacci-like sequence with different starting values. We can find the subsequent terms using the given rule:

Term 1: 3
Term 2: 5
Term 3: 3 + 5 = 8
Term 4: 5 + 8 = 13
Term 5: 8 + 13 = 21
Term 6: 13 + 21 = 34
Term 7: 21 + 34 = 55
Term 8: 34 + 55 = 89

Thus, the value of the eighth term in the sequence is 89.
