Answers with Solutions
1.(b)
Clearly, we have: 2 x 2 + 1= 5, 5 x 2 -1 = 9, 9 x 2 + 1 = 19, 19 x 2 -1 = 37,
So, missing term = 37 x 2 + 1 =75.
2.(a)
The pattern is +2, +4, +8, +16
So, missing term = 28 + 8 = 36.
3.(d)
Clearly, the given the series consists of cubes of odd numbers and squares of even numbers, I. e, 13, 23, 33, 43, ….
So, missing term = 53 = 125.
4.(a)
Clearly, the numerators of the fractions in the given sequence form the series 1, 3, 5, 7, in which each term is obtained by adding 2 to the previous term.The denominators of the fractions form the series 2, 4, 8, 16, i.e. 21, 22, 23, 24.So, the numerator of the fractions will be (7 +2) i.e. 9 and the denominator will be 25 i.e. 32.
Thus, the next term is 9/32.
5.(b)
The given series consists of squares of consecutive odd numbers i.e. 12, 32, 52,72,…… So, missing term = 92 =81
