Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression
n = 1 → 1² + 1 = 1 + 1 = 2
n = 2 → 2² + 2 = 4 + 2 = 6
n = 3 → 3² + 3 = 9 + 3 = 12
n = 4 → 4² + 4 = 16 + 4 = 20
n = 5 → 5² + 5 = 25 + 5 = 30

Answer:
RQ = 9.
Step-by-step explanation:
m < RPQ = 180 - 90 - 75 = 15 degrees
m < PQM = 75 - 60 = 15 degrees.
So triangle PMQ is isosceles so side PM is congruent to side MQ, therefore MQ = 18.
Triangle RQM is a 30-60-90 triangle with RQ the shortest leg (because it is opposite the lowest angle) so that makes RQ = 1/2 of MQ. (The sides in a 30-60-90 triangle are in the ratio 1:sqrt3:2)
RQ = 1/2 * 18 = 9.
It’s c i think or can be d but my best bet is c !!
