What is the missing number? 1350,1150, $$ \qquad $$ 750

Question

UpStudy AI · Accepted Answer

1. Let the four numbers in the sequence be $$ a = 1350 $$, $$ b = 1150 $$, $$ c $$ (the missing number), and $$ d = 750 $$.

2. Assuming the sequence is arithmetic, the difference between consecutive terms is constant. Let the common difference be $$ r $$. Then:
   $$
   b = a + r, \quad c = b + r, \quad d = c + r.
   $$

3. We have:
   $$
   b = 1350 + r = 1150 \quad \Rightarrow \quad r = 1150 - 1350 = -200.
   $$

4. Now, calculate the missing term $$ c $$:
   $$
   c = b + r = 1150 + (-200) = 950.
   $$

5. Thus, the missing number is $$ \boxed{950} $$.
The missing number is 950.
