Step-by-step explanation: -91, -34, 12, 50.8
Answer:
see explanation
Step-by-step explanation:
Note the common difference d between consecutive terms
d = 10 - 3 = 17 - 10 = 24 - 17 = 7
This means the sequence is arithmetic with n th term
= a₁ + (n - 1)d
Here a₁ = 3 and d = 7, thus explicit formula is
= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4, thus
= (7 × 18) - 4 = 126 - 4 = 122
Answer:
6.4
Step-by-step explanation:
A^2+B^2=C^2
(5*5)+(4*4)=C^2
25+16=
