Question

19, 27,0,64,?, 155
a)-61
c)-23
b)83
d) 47​

Answer 1

Answer:

(a) - 61

Step-by-step explanation:

According to this question

We have been given that

19, 27, 0, 64, ?, 155

$19 + 2^3$ = 19 + 8 = 27

$27 - 3^3$ = 27 - 27 = 0

$0 + 4^3$ = 0 + 64 = 64

$64 - 5^3$ = 64 - 125 = - 61

$-61 + 6^3$ = -61 + 216 = 155

So, 19, 27, 0, 64, -61, 155

Answer 2

Given: The given series is 19, 27,0,64,? 155.

To find: We have to find the missing term.

Solution:

To determine the missing term in the series we have to determine the pattern of the above series.

The given series is 19, 27,0,64,? 155.

Let the missing term be x.

The series follows a specific pattern.

The pattern is as follows-

$19 + {2}^{3} = 27 \\ 27 - {3}^{3} = 0 \\ 0 + {4}^{3} = 64$

In the same pattern, the next term x will be-

$x = 64 - {5}^{3} \\ x = 64 - 125 \\ x = - 61$

Thus, the value of x is -61.

So, the missing term in the above series is -61.
