The sequence alternates between multiplying by 2 and then subtracting 3. Starting with 5, you multiply by 2 to get 10, then subtract 3 to get 7, multiply by 2 to get 14, subtract 3 to get 11, multiply by 2 to get 22, and subtract 3 to get 19. Following this pattern, the next operation is to multiply 19 by 2, resulting in 38. Therefore, the next number in the series is 38.
Call the unknown number n. Then, from the problem statement, {4[(n + 7 - 2) - n]} - 2 = 18. This is always true because [(n + 7 - 2) - n] is simply 5.
3.75 and the word is subtract, not substract.
When you multiply a number by 8 and subtract 5, you can express this operation mathematically as ( 8x - 5 = w ), where ( x ) is the original number. To isolate ( x ), you would rearrange the equation to find ( x = \frac{w + 5}{8} ). This gives you the original number in terms of ( w ).

Using algebra the number works out as 25
2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.

365 would be next because you multiply the last number by three then subtract one.
