Which number will come next in the following series? 675, 623, 573, 525?

Option b: 479. Solution: To find the next term in the series 675, 623, 573, 525, ? , we analyze the differences between consecutive terms: - 1st term to 2nd term: 675 - 623 = 52 - 2nd term to 3rd term: 623 - 573 = 50 - 3rd term to 4th term: 573 - 525 = 48 We observe that the difference between terms is decreasing by exactly 2 at each step ( 52, 50, 48, ... ). Following this logical pattern, the next difference must be 46 . We subtract 46 from the 4th term ( 525 ): 525 - 46 = 479 Hence, Option B is the correct answer.

Which number will come next in the following series? $675, 623, 573, 525?$

The correct answer is Option b: $479$. To find the next term in the series $675, 623, 573, 525, ?$, we analyze the differences between consecutive terms: - 1st term to 2nd term: $675 - 623 = 52$ - 2nd term to 3rd term: $623 - 573 = 50$ - 3rd term to 4th term: $573 - 525 = 48$ We observe that the difference between terms is decreasing by exactly $2$ at each step ($52, 50, 48, \dots$). Following this logical pattern, the next difference must be $46$. We subtract $46$ from the 4th term ($525$): $$525 - 46 = 479$$ Hence, **Option B** is the correct answer.

All Options:

A $\displaystyle 491$
B $\displaystyle 479$
C $\displaystyle 423$
D $\displaystyle 456$

Detailed Solution & Explanation

To find the next term in the series

\displaystyle 675, 623, 573, 525, ?

, we analyze the differences between consecutive terms:

- 1st term to 2nd term:

\displaystyle 675 - 623 = 52

- 2nd term to 3rd term:

\displaystyle 623 - 573 = 50

- 3rd term to 4th term:

\displaystyle 573 - 525 = 48

We observe that the difference between terms is decreasing by exactly

\displaystyle 2

at each step (

\displaystyle 52, 50, 48, \dots

).
Following this logical pattern, the next difference must be

\displaystyle 46

. We subtract

\displaystyle 46

from the 4th term (

\displaystyle 525

525 - 46 = 479

Hence, **Option B** is the correct answer.
