• D. 455

Answer 1

Answer:

B. 454

Series:
419, 424, 430, 437, 445, ?

Step 1: Find the differences

• 424 − 419 = 5

• 430 − 424 = 6

• 437 − 430 = 7

• 445 − 437 = 8

Step 2: Observe the pattern

The differences are increasing by +1 each time:

+5, +6, +7, +8

Step 3: Find the next difference

Next difference = +9

Step 4: Find the next number

445 + 9 = 454

454
