7ab + 5 is going to be the answer because I solved it and that's the answer
From 10 to 15 -> 10 increased with half its size (5), that means increase of 50%
From 16 to 12 -> decrease of 4, which is a quarter of 16, that means a decrease of 25%
Answer:
= 2n + 3
Step-by-step explanation:
This is an arithmetic sequence with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 2 , then
= 5 + 2(n - 1) = 5 + 2n - 2 = 2n + 3
