Question

f(1)=2 f(n+1)=f(n)+4 What is f(10)? Enter your answer as a number, like this: 42

Answer 1

Answer:

if f(1) =2 then

f(1) = f(0) +4

f(0) = -2

f(2) = 2 +4 = 6

so each number has a gap of 4

so we can search it with

a = 2

b =4

a+ 9b = 2+ 36 = 38

answer = 38

Answer 2

Step-by-step explanation:

f(10)= 2+9×4=38

f(n) is in A.P. whose first term is 2 and common difference is 4.
