what is the next number in the sequence 1, 121, 12321, 1234321, ?

the next number in the sequence is

The next number is 123454321

Step-by-step explanation:

Given the sequence of numbers

1, 121, 12321, 1234321, ...

we have to find the next number in the sequence.

First number - 1

Second number- 121

Third number - 12321

Fourth number - 1234321

we have to find the fifth number

In the first term the number is 1. The second term starts from zero goes to 2 then end with 1. Third number starts wit 1 goes to 3 and then end with 1. Fourth number starts with 1 goes to 4 ten end with 1.

Similarly follow same manner

Fifth term starts with 1 goes to 5 then end with 1 i.e 123454321

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

i think the answer is true
