Answer:
Forth term of the sequence is 61
Step-by-step explanation:
Let's just go from a1 to a4:
a1 = 5
a2 = 2x5+3 = 13
a3 = 2x13+3 = 29
a4 = 2x29+3 = 61
313,626 = 2 * 152,346 + 8934
152,346 = 17 * 8,934 + 468
8,934 = 19 * 468 + 42
468 = 11 * 42 + 6
6 divides 42, so the GCD of 313,626 and 152,346 is 6.
