Missing Number (SSC MTS 2022 Tier -1)

(First number + Third number) ÷ 2 = (Second number)

(80, 64, 48) → {(80 + 48) ÷ 2} ⇒ 128 ÷ 2 = 64

(112, 96, 80) → {(112 + 80) ÷ 2} ⇒ 192 ÷ 2 = 96

Similarly,

(232, 216, ?) → {(232 + 200) ÷ 2} ⇒ 432 ÷ 2 = 216

Hence, "200" is the correct answer

(First number × Third number) = (Second number)

(7, 343, 49) → (7 × 49) = 343

(6, 216, 36) → (36 × 6) = 216

Similarly,

(5, 125, ?) → (5 × 25) = 125

Hence, "25" is the correct answer.

(First number + Second number) = (Third number)

(8, 96, 104) → (8 + 96) = 104

(11, 132, 143) → (11 + 132) = 143

Similarly,

(7, 84, ?) → (7 + 84) = 91

Hence, "91" is the correct answer.

{(First number + Third number) ÷ 2} = Second number

(68, 56, 44) → {(68 + 44) ÷ 2} ⇒ 112 ÷ 2 = 56

(245, 233, 221) → {(245 + 221) ÷ 2} ⇒ 466 ÷ 2 = 233

Similarly,

(97, 85, ?) → {(97 + 73) ÷ 2 } ⇒ 170 ÷ 2 = 85

Hence, "73" is the correct answer.

First number + 8 = Second number & Second number + 8 = Third number

(11, 19, 27) → (11 + 8) = 19 & (19 + 8) = 27

(17, 25, 33) → (17 + 8) = 25 & (25 + 8) = 33

Similarly,

(23, 31, ?) → (23 + 8) = 31 & (31 + 8) = 39

Hence, "39" is the correct answer.

{(First number + Third number) ÷ 2} = Second number

(38, 43, 48) → {(38 + 48) ÷ 2} ⇒ (86 ÷ 2) = 43

(76, 81, 86) → {(76 + 86) ÷ 2} ⇒ (162 ÷ 2) = 81

Similarly:

(69, 74, ?) → {(69 + 79) ÷ 2} ⇒ (148 ÷ 2) = 74

Hence, "79" is the correct answer.

First number + 11 = Second number & Second number + 11 = Third number

(74, 85, 96) → 74 + 11 = 85, 85 + 11 = 96

(67, 78, 89) → 67 + 11 = 78, 78 + 11 = 89

Similarly:
(84, 95, x) → 84 + 11 = 95, x = 95 + 11 = 106

Hence, "106" is the correct answer.

First number × 4 = Second number & Second number + 4 = Third number

First row → 30 × 4 = 120 & 120 + 4 = 124

Second row → 40 × 4 = 160 & 160 + 4 = 164

Similarly,

Third row → 22 × 4 = 88 & 88 + 4 = 92

Hence, "92" is the correct answer.

{(First number + Third number) ÷ 2} = Second number

(47, 82, 57) → {(47 + 57) ÷ 2} ⇒ 104 ÷ 2 = 52

(69, 74, 79) → {(69 + 79) ÷ 2} ⇒ 148 ÷ 2 = 74

Similarly,

(86, 91, ?) → {(86 + 96) ÷ 2} ⇒ 182 ÷ 2 = 91

Hence, "96" is the correct answer.

{(Third number + First number) ÷ 2} = Second number

(12, 19, 26) → {(26 + 12) ÷ 2} ⇒ 38 ÷ 2 = 19

(28, 35, 42) → {(42 + 28) ÷ 2} ⇒ 70 ÷ 2 = 35

Similarly,

(39, 46, ?) → {(53 + 39) ÷ 2} ⇒ 92 ÷ 2 = 46

Hence, "53" is the correct answer.
