Question

4, 11, 19, 41, ?, 161 A) 62 B) 108 C) 79 D) 90 E) 85

Answer 1

Given: The series 4, 11, 19, 41, ?, 161

To find: The missing term ?

Solution:

• Now we have given the series as:

                4, 11, 19, 41, ?, 161

• Now the logic can be found out as:

• For second term, we have:

                4 × 2 + 3 = 11

• For third term, we have:

                11 × 2 - 3 = 19

• Similarly:

                19 × 2 + 3 = 41

• So for the fifth term, we have:

                41 × 2 - 3 = 79

• And for fifth term, we have:

                79 × 2 + 3 = 161

• So the fifth term is: 79

Answer:

           The correct option is C) 79.

Answer 2

Qᴜᴇsᴛɪᴏɴ :-4, 11, 19, 41, ?, 161 A) 62 B) 108 C) 79 D) 90 E) 85

Sᴏʟᴜᴛɪᴏɴ :-

Lets See the Pattern here :-

→ 4 * 2 + 3 = 11

→ 11 * 2 - 3 = 19

→ 19 * 2 + 3 = 41

→ 41 * 2 - 3 = 79

So, we can conclude that, pattern is of Multiply by 2 the previous number and adding and subtracting 3 alternatively .

Now Lets check if it fits the Next also .

→ 79 * 2 + 3 = 161 (Verify).

Hence, 79 (C) is correct Answer.
