How many such 5s are there in the following sequence that the sum of the two immediately following digits is greater than the sum of the tw…

Solution
Given sequence 3 7 6 5 8 3 2 4 5 5 4 8 7 9 1 5 3 4 8 7 5 9 8 7 6 4
5's for which the sum of following two digits is greater than the sum of preceding two digits are highlighted below
3 7 6 5 8 3 2 4 55 4 8 7 9 1 5 3 4 8 7 5 9 8 7 6 4, Thus there are 3 such 5's so option 3
