Compilation - Progression

Type Of Problems Complete Collection



Type 1
how many terms are same in two sequence. get the nth term formula and equate it in such a way that by placin m you should be able to get n. these two will form a series, the on which has high d i.e the one which will exhaust fast take out how many terms that series will contain. and this number should be less than 100 or whatever the limit given in question.
thats your answer
Type 2
finding number of terms. arithmetic mean concept will be used.
two extreme values will be given and ratio of two terms will be given.
we'll use d=(b-a)/(n+1)
1 term a+d, 2nd a+2d ..
sum ratio is given 10th term ratio is asked.
multiply the term formula by 2 and get value of n by corresponding it to summatio ratio.
Type 3
odd even split in series. difference in odd even is nd if number of term are even.
Type 4
geometric figure one inside another infinetlly.
sum of angle in arithmatic progression.
