Correct Answer:
Second option
Solution:
The given sequence is:
2.2, 6.6, 11, ...
If we observe the sequence it is an Arithmetic Sequence as the difference between two consecutive terms is the same.
6.6 - 2.2 = 4.4
11 - 6.6 = 4.4
First we find the general term for this sequence.
first term = 2.2
d = 4.4
So,
This general term will be placed inside the summation sign with limits from 1 to 5 to give the sum of first 5 terms of the given sequence. So the correct answer is Second Option

The value of the given equation is –0.37458.
Solution:
Given equation is:
Let us first find the values.
The value of tan 1.1 = 1.96475
The value of tan 4.6 = 8.86017
Substitute these values in the given equation.
= –0.37458
Hence the value of the given equation is –0.37458.
