New sequence is as follows:
pr1 qr2 pr3 pq4 qr5 rp6 qq7 rp8 qp9 qr10 qp11 qp12
16th from the right end is 7
The series consists of 2 groups (A, B, C, D, E, F, ?, ?) and (N, O, P, ?). The series is made of two terms of first group followed by one term of second group.
The letters move five steps forward.
The correct pattern is +4,+7,+10,+13,+16
So, 36 is wrong term and it must be replaced by 25+13=38
The given sequence is a combination of two series
1)31,35,39,43,47
2) 45,47,49,51,53
So,the missing term is 49
Here it can be seen that it is not a continuous series.
so take alternative terms.
CGE, FJH, IMK and RNP, OKM,__
Between R and O there is a gap of two letters. so the first letter in the answer is L.Proceding like this the answer is LHJ
The first letter moves three steps forward. The second letter moves two steps forward. The third letter moves three steps forward.
Here the given number series 625, 625, 600, ?, 475, 875 follows a pattern that
625
625 + (0 x 0) = 625
625 - (5 x 5) = 625 - 25 = 600
600 + (10 x 10) = 600 + 100 = 700
700 - (15 x 15) = 700 - 225 = 475
475 + (20 x 20) = 475 + 400 = 875
Hence, the missing number in the given number series is 700.
The given number series 999, 990, 998, 991, 997, 992, ?
It follows a pattern that,
999
999 - 9 = 990
990 + 8 = 998
998 - 7 = 991
991 + 6 = 997
997 - 5 = 992
992 + 4 = 996
Hence, the next number in the given number series is 996.
The pattern is + 6, + 12, + 18, +24 ...........So the missing term is = 68 +30 = 98
