This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by <span>33</span> gives the next term. In other words, <span><span><span>an</span>=<span>a1</span>⋅<span>r<span>n−1</span></span></span><span><span>an</span>=<span>a1</span>⋅<span>r<span>n-1</span></span></span></span><span>.</span>

Answer: 12%
Step-by-step explanation:
Let the original salary be Rs a
Salary after increase = a + 40% of a
= a + 40a/100
= 140a/100
= 14a/10
= 7a/ 5
Salary after Decrease = 7a/5 - 20% of 7a/5
= 7a/5 - 20× 7a / 100 × 5
= 7a/5 - 7a/25
= ( 35a - 7a) / 25
= 28a/25
Absolute increase = 28a/25 - a
= 3a/25
Percentage = 3a/25 ×100 / a
= 3 × 4
= 12%
