Question

1,-12,42,-104,210,-372,602,-912,1314,_,2442,-3192 find missing value by brainly​

Answer 1

Given:

1,-12,42,-104,210,-372,602,-912,1314,____,2442,-3192

To Find:

Find the missing value

Solution:

We need to find a pattern in the sequence, for this sequence the pattern is as follows,

1

-(4*3)

6*7

-(8*13)

10*21

the left side numbers gradually increase by 2 and for the right side number the number increases by the value of the left side of the previous equation

for example- previous value 4*3

                     next value 6*(3+4)=6*7

and also every alternative value becomes negative

so following this pattern

12*31=-372

14*43=602

16*57=-912

18*73=1314

20*91=-1820

22*111=2442

Hence, the missing value is -1820.
