Select the number from the given options to complete the series. 35, 38, 43,…

To find the missing number in the series 35, 38, 43, 50, 59, __, we need to analyze the differences between consecutive terms.

Analysis of the Pattern
Let's calculate the differences between each pair of numbers:

38 - 35 = 3

43 - 38 = 5

50 - 43 = 7

59 - 50 = 9

The differences are 3, 5, 7, 9, which are consecutive odd numbers. Following this pattern, the next difference should be the next odd number, which is 11.

Calculation
Adding the next difference to the last term in the series:
59 + 11 = 70
