The nth term of a sequence is always in the form of _n + _
From the sequence, we can see that each number is differing by 6
If we add up 6 to the first number of the sequence, we get 95, so, as to make the sequence flow
and If we substract 6 from any of them we get the next number, right?
SO, considering 95 ,the nth term will be
95-6n
Basically, Its more like Since we are subtracting six SO six should be the first number.. SO from left to right we are subtracting, from right to left we will add.. Adding up 6 to the first number turns out to be 95, As the sequence is from left to right so it'll be 95-6n

Please help me in s15 qp 12 q 26 about patterns
Click to expand...
theres this one simple formula for these kinda patterns with uniform difference
= a+(n-1)d
a is the first term here
in the qs here it is 89
and d is the difference between two consecutive terms
for the diference subtract the second term from the first term
in this case its 83-89=-6
so putting up the values
=89+(n-1)-6
=89-6n+6
=95-6n <---
