Answer: C The first letter of each group moves +2, second letters moves +2 and the third letter moves +2 steps. Thus, W + 2steps = Y; V+2steps = X; U+2 steps = W Thus, the answers is YXW.
Q. No. 3:
The next term in the series 4,8,28,80,244, (..?..) is :
Answer: D The first letter of each group moves +1 steps, second letter moves (-1) step and the third letter moves (-2) steps. Thus the next group of letters would be 'roa'.
Q. No. 5:
The next term in the series 3,10,29,66,127, (..?..) is :
Answer: C 3, 10, 29, 66, 127, x Thus, the difference between the numbers => (10-3), (29-10), (66-29), (127-66), (x-127) => 7 , 19, 37, 61 x-127 Now, the difference between these numbers => 12, 18, 24, x-188 [Form an A.P with common difference of 6] Thus, x - 188 = 30 => x = 218.
Q. No. 6:
What is the missing element in the sequence represented by the question mark ? P3C, R5F, T8I, V12L, (..?..)
Answer: C The first letter in each group P +2 = R, R +2 = T, T +2 = V , V +2 = X The second letter, 3 +2 = 5, 5 +3 =8, 8 +4 = 12, 12 +5 = 17 The third letter, C+3 = F, F +3 = I , I + 3 = L, L+ 3 = O
