litterally you are lazy, search it up, https://math.stackexchange.com/questions/2104450/120-60-80-90

Literally you are 3 weeks late

at this point i would just drop out of that course, there is no hope.

Answer is my fine sir: 96

How you do it is 120 divided by 5= 24
24 times 4 = 96
But then you also think about, its the 5th number in sequence so the answer could also be 120.

It's a terrible question unless you've missed out a key part of the question. There are multiple perfectly valid answers, mostly listed on the stack exchange post @Creepis linked.

Most obvious option is that fraction thing though: a_0=120, a_n = a_0(n/(n+1)) where n>1.

Sorry, what's the answer...?

@Exrobite come on math wizz kid

With some rather simple math, i get this:


∑n=1∞n3(132+103+32√+64+2x52+2x132103+32√√2242)n=42∑n=1∞n3(132+103+32+64+2x52+2x132103+322242)n=42

Simple math my arse. If that was simple maths I wouldn't have scored the lowest grade possible on my maths GCSE. To me, that looks like a crackhead on sniff tried to type the answer to 21+21. What tf are those ticks and weird Ms on their side and the two oo anyways?

What tf are those ticks anyways?

Square roots...

Square roots...

What tf is that?

12 squared is 144. So the square root of 144 would be 12. No offence but someone in year 4 could have answered that.

In year 4 I was still struggling with adding and subtracting. I still don't know my time's tables. I don't know where you got that 12 from tho? Why not use 15?

You can use 15, it was just an example.

Oh, So what are those weird pushed over Ms then?

If you don't understand what square roots are, you'd have no chance understanding A level maths and algebraic functions.

Forget I asked. To me those letters look like a spider ran in ink and then had a stroke then died on a piece of paper

 

[rogue]

dunno mate

 

[CodezBlack]

Why would the Military even ask you this you don't really need to be good at maths if you are Infantry, All you need to be is Fit, Know how to use a weapon, Know how to not die.

 

[rat]

as a maths expert i can say for certain that the answer is trivial and left as an exercise for the reader
