which number best completes the sequence 1 1 3 2 4 6 5 25

[Ken Sp.]

Carm--choices on number 2 were 2, 15, 18, 32, 28?

A good friend took this test yesterday, and he knows l like these things so he forwarded some to me--and I was stumped on these 3. It may be due to the late hour--and at 50 years old--it has been awhile since I have done these.

Thanks again so much...Once I see your sequence--I kick myself--since it is now so clear :-)
