I was doing english exercises about the different types of future, when I saw "will be going to" among the answers I could give to a question. I've never heard it before, my teacher says it can be used but I looked for it in the internet and it doesn't exist. So, is it correct to say "will be going to"?
I think this depends on whether you mean to use the phrase with a place or another verb. You can say:
I will be going to America next year / I'll be going to bed soon / I'll be going to the show too.
However if you mean 'to' as part of an infinitive verb then it doesn't work. Compare:
- I am going to drive to the shop.
- I will be going to drive to the shop.
(1) makes perfect sense. Although it uses the present tense 'am', the use of 'going' implies it is something that will be done in the future. (2) does not make sense.
This is an example of future continuous tense.
It is just a combination of future tense ("will" + infinitive) and present continuous ("am/are/is" + present participle). In other words, it's like converting
I am going to …
into future tense.
It is a warm afternoon — too warm — sunny afternoon in late January as I write this. If I didn’t know better, I might even think that the frogs were going to arrive a month ahead of schedule this year. But there will be more of the cold white death before the green of life wins out again, announced by those little frogs who know better than I how to await the inevitable coming of a spring which I’m too anxious for.

Modifying the verb tense of the clause “the frogs were going to arrive a month ahead of schedule” to future, the correct form of “were going to arrive” becomes
a) is going to arrive.
b) would be arriving.
c) have just arrived.
d) was going to arrive.
e) will be going to arrive.
