200 r 351 ...............
Answer:
The next term in the given series is 326.5
Step-by-step explanation:
The given series is 124.5, 100, 200, 175.5, 351
The series proceeds in such a way that the terms in the even positions are obtained by subtracting 24.5 from the previous term. The terms in the odd positions(except the first term) are obtained by doubling the previous term.
Step 1:
First term = 124.5
Second term = First term - 24.5
Second term = 124.5 - 24.5
Second term = 100
Step 2:
Second term = 100
Third term = 2 × Second term
Third term = 2 × 100
Third term = 200
Step 3:
Third term = 200
Fourth term = Third term - 24.5
Fourth term = 200 - 24.5
Fourth term = 175.5
Step 4:
Fourth term = 175.5
Fifth term = 2 × Fourth term
Fifth term = 2 × 175.5
Fifth term = 351
Step 5:
Fifth term = 351
Sixth term = Fifth term - 24.5
Sixth term = 351 - 24.5
Sixth term = 326.5
Therefore, the next term in the series is 326.5
