ഉപയോഗിച്ചിരിക്കുന്ന ആശയം:

a, b, c… എന്നിങ്ങനെ ആവട്ടെ നമ്മുടെ സമാന്തര ശ്രേണി 

പൊതുവ്യത്യാസം നമുക്കറിയാം = b - a, c - b.

സമാന്തരശ്രേണിയിലെ പൊതുവ്യത്യാസം സമമായിരിക്കും

b - a = c - b

കണക്കുകൂട്ടൽ:

b – a = c – b

⇒ b + b = c + a

⇒ 2b = c + a

⇒ 2b = a + c

∴ a, b, c എന്നിവ സമാന്തര ശ്രേണിയിലാണ്. അപ്പോൾ 2b = a + c.

AP യിലുള്ള സംഖ്യ 1, 2, 3 ആയിരിക്കട്ടെ

ഒരു ഓപ്ഷൻ മാത്രമേ സമവാക്യത്തെ തൃപ്തിപ്പെടുത്തിയിട്ടുള്ളൂ

2 (2) 1 + 3 = അതിനാൽ 2b = a + c ശരിയായ ഓപ്ഷനാണ്.
