Answer:

793 will be the next term in the series.

Explanation:

From the given question : 3,15,38,78,141,235,370,552,x

We need to find the value of x.

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown".

11, 17, 23, 31, 41, and 47 are prime numbers.

Also, if we make a series of prime numbers starting from 11m we will get:

11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, and 59.

Clearly, 11, 17, 23, 31, 41, and 47 are alternate numbers in the above series.

Thus, the next number will be 59. 59 + 182 = 241 241 + 552 = 793

Hence, 793 will be the next term in the series.
