Mark the values which are considered as spikes in the data

The data is contained within a column vector. I need to find the so called spikes i.e. find their indices so I can later replace those values using linear interpolation. In the question it says: Consider a spike when the difference between consecutive values is larger than 750.

I am assuming I need to write a for loop to iterate through the vector and compare each element with the one before it, but since I am new to Matlab I am not sure how to approach this.

Thank you

I believe findpeaks or isoutlier will detect spikes.

To investigate which (or some other) method will work, could you upload a sample data if possible?
