i checked my old blockchain.info backup and their recovery phrase used to be 19 words long. you may be missing a word or two there. i say may because they changed their system a couple of times!
also if you are having trouble with a specific word, you may be typing it wrong.

try this link for your recovery:
https://blockchain.info/wallet/forgot-password

also try this for the word list to check against your words:

i googled a little and i can see others wanting to recover saying they have 17 words. mine is for 2 or more years ago and it is 19 words and these days the new version is 12 words! so they have changed it around a lot.

my guess is you wrote down one of the words wrong. check the spelling versus the word list.
also try contacting their support team: https://support.blockchain.com/hc/en-us

i can't think of any other reason. maybe someone else has any other ideas.
