ok so u have to find the formula first cz they cn ask u to find the 100th term n u wudnt know in the world how to by goin till the hundreth one :P
seee sinch the commmom difference is 3.....and wheneva u have found the common difference u have to apply the formula which is: commom difference times n(n is the no. of term in this case 12) + b
so here it is 3n+b
now u have to find b!
use 1st term as n to find b - 3*1+b= 5
3+b=5
b=2 now uve found the final formula which 3n+2!
so now use 12 as n
3*12+2= 38 ;)
note that the common difference can also be a negative term for e.g if ur sequence is 14,11,8..
this time the common difference is -3...and ur formula will be
-3n+b...work it out as ive shown above and ur fourth term should be 5!
wth this formula u cn even find the ten thusanth term... =D
hav a good day!

The twelfth number in the sequence is 38 as shown above with each number increasing by three on the previous one.

Yes it's 38 if you are looking for the 12th number in this series. the commonality is that each number increases by 3
