how to tackle these types of questions (sequence and series)
I did the theory of ap gp and even practiced a few questions (jee level) but i feel every question in ipmat has a long method (or ig i have learned it without shortcuts) i also solved 2025 pyq all felt like each of them wouldrake like 10 mins to solve like so many cases and caluations
if anyone has have any shortcuts and good notes for revision overall can youll send me

honestly don't these qns are often meant to be skipped
hii scraggy any suggestions for VA im almost clearing the cutoffs in QA I dont want VA to block my way to indore as i have a overall good profile too so im just scared of getting shortlisted rather than being selected
IN RC i almost get 10 questions correct
sentence completion is getting better
parajumbles and grammar are giving hella negatives
cloze para is just 50-50
Jiya also helped me which improved my score a bit but yet a day im on 108 the next i fall back on 70-90(as RC in the mock is hard ig)

tho if you want a sol here you go
Let first term = a, common ratio = r
p-th term: a r^(p−1) = q
q-th term: a r^(q−1) = p
Divide:
r^(p−q) = q/p
Take logs:
(p−q) log r = log(q/p)
Now from first equation:
log a + (p−1) log r = log q
Substitute log r:
log a = log q − (p−1) * [log(q/p)/(p−q)]
Simplifying gives:
log a = [(1−q) log p − (1−p) log q] / (p−q)
