Answer: The answers are (a) 5.3 km, (b) Yes, (c)
Step-by-step explanation: Given that a walker is walking 5 km per day and he decides that he will increase the distance by 0.1 km per day from 1st August.
(a) On 1st August, he will be walking (5+0.1) = 5.1 km.
On 2nd August, he will be walking (5.1+0.1) = 5.2 km.
On 3rd, August, he will be walking (5.2+0.1) = 5.3 km.
(b) Yes, this sequence is an arithmetic sequence with first term, a = 5.1 and common difference, d = 0.1. Because, the distance 0.1 km is being added, not multiplied.
(c) The formula for the n-th term will be
Thus, the answers are completed.
