In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. a) 216 b) 218 c) 221 d) 223

The arithmetic sequence with the given condition is determined recursively by

So we have

and so on with the general pattern

This means the 72nd term in the sequence is

so the answer is B.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

1010: 3030

is it i think
