Hello! ) this is math : ( can you me ?

An explicit formula is used to find any term in a sequence by putting in the number of that term in place of the unknown variable.

In order to find the first four terms, we need to plug values, from 1-4, separately in each of the formulas.

For f(n) = 7(n+1) - 11, put values from 1-4 in place of n:

f(1) = 7(1+1) - 11 = 3 > First term

f(2) = 7(2+1) - 11 = 10 > Second term

f(3) = 7(3+1) - 11 = 17 > Third term

f(4) = 7(4+1) - 11 = 24 > Fourth term

For f(n) = 65 - 10n, put values from 1-4 in place of n:

f(1) = 65 - 10(1) = 55 > First term

f(2) = 65 - 10(2) = 45 > Second term

f(3) = 65 - 10(3) = 35 > Third term

f(4) = 65 - 10(4) = 25 > Fourth term
